Travel Diary #3: Road trip in Madagascar 5828

Antoine, 9 mon.
For safety reasons and due to the roads/tracks conditions, we rented a 4x4 with a driver for our stay in Madagascar. What a great idea it was! You’ll understand why in a bit. Let’s start at the beginning. We stayed for two nights in central Antananarivo to discover the city and also rest a little. The city is located at an altitude of about 1,200 meters, and the streets are far from flat. After several weeks of safaris by car, our bodies were in dire need of some excercise. We explored the city on foot. And then, we hit the road. We met the rental agency manager on the morning of our departure, who informed us that the transmission in the car we were supposed to get was broken. So, we would have a car and a driver for the day, and our guide would meet us the following day. Off we went to Antsirabe. At lunchtime, to our surprise, we made a stop in a town known for... foie gras. Delicious! The next day, we met our driver, Georges. My son was having some digestive issues, thankfully, the main ingredient in all three daily Malagasy meals is rice. Georges suggested we spend the night at his aunt’s house in Miandrivazo, where we had Malagasy chicken soup for dinner. This chicken was raised outdoors, freely roaming the village streets. It was cooked in a broth with some ginger and rice. The next day, my son was completely healed. We continued driving to Morondava, a coastal town to the west, at the end of RN35. It was just a stopover before heading the next day towards Bekopaka. Unfortunately, after about an hour of driving, the car started emitting white smoke. So, we stopped and waited for a new car and driver, while Georges handled the necessary repair. The car’s turbo had broken. With our new driver, we headed towards the Kirindy Forest. Since we lost some time, it was impossible to reach Bekopaka before nightfall. That evening, we went on a guided tour of the forest to observe several species of nocturnal lemurs. The next morning, after a short tour to observe the diurnal lemurs with the same guide from the previous day, we headed to Bekopaka. The two river crossings were done by ferry. These ferries are essentially wooden motorized bridges that fit five vehicles side by side. The next day, we visited the Tsingy de Bemaraha, a UNESCO World Heritage site. These are sharp black limestone formations (due to oxidation) rising up to 700 meters high. The hike lasted about 4 hours and included parts of a via ferrata. The views were absolutely breathtaking. We then returned to Morondava, completing the 10-hour drive in one day. The following day, we reunited with Georges to continue our journey towards Belo sur Mer. We took the opportunity to go for a sailing pirogue ride. Two people navigate the pirogue: one manages the tension of the sail and paddles that serve as a rudder, while the other is at the front, handling the sail. The person at the front sits on a wooden plank connecting the pirogue to a counterweight about 10 cm wide. He seemed comfortably settled for the 3-hour journey to a small island in the turquoise waters where we had a picnic. To travel further down the west coast of Madagascar, we took a small detour inland through the town of Manja. On the dirt road, a small river crossing in the 4x4 had surprised our driver with its depth. The next day, we realized there was water in the reservoir. As we turned back, the steering axis broke. We ended up at the small restaurant we had just passed earlier. The method for getting there without a steering axis was rather amusing. While the driver was at the wheel, I walked alongside the car, manually turning the wheels of the 4x4 to steer it in the right direction. Once at the restaurant we met a driver who took us directly to the town of Ifaty. We canceled the further coastal towns to the north that required a functional 4x4. The road was asphalted, but there was no bridge yet to cross the river. The local pirogue operators took the initiative to organize a crossing service. Six pirogues, joined together by planks of branches nailed together, welcomed one car at a time. The pirogue operators, standing in the river as water level is low during the dry season, pushed the boats to the other side. A few days in Ifaty while waiting for a new car allowed us to rest a bit and go for a snorkeling trip. The corals and fish were beautiful. After this break, we got a new car and driver to take us to Isalo National Park. This park is made up of mountains in the middle of the desert, with a verdant canyon running between them. We did an 8-kilometer hike, in about 6 hours, allowing time for a swim in two waterfalls. We saw numerous species of insects and animals, including the famous ring-tailed lemurs. One particularly surprising insect we encountered was the stick insect, which is barely distinguishable from the branch of a bush. Without our guide, we would never have spotted it. The next day was a long drive to reach Ranomafana National Park, another UNESCO World Heritage site. We did another 8-kilometer hike the following day, which took us about 3.5 hours through its tropical rainforest. We only hiked in the secondary forest, as the primary forest is only accessible to the most adventurous who venture deep into the park for several days. These 3.5 hours were filled with new encounters. We observed five different species of lemurs, including the golden bamboo lemur, first identified in 1986 by primatologist Patricia Wright. At the end of the hike, we happened to meet her, accompanied by one of her students—what a coincidence! We chatted for a few minutes, and she mentioned the screening of her new documentary in the town of Ranomafana that evening. Unfortunately, we couldn’t attend as we had to head to Ambositra, about 3 hours north. After a night in Ambositra, we headed to Antsirabe. This time, we visited the surrounding area. We went to Lake Tritriva, a sacred lake for the Malagasy people. We could walk around the lake and swim in it. This lake is in the crater of a volcano and is about 140 meters deep. A legend says that Rabeniomby and Ravolahanta (the Malagasy Romeo and Juliet) committed suicide there. The next day, we returned to Antananarivo. During the long hours of driving throughout this road trip, withou our drivers and other people, we had the chance to discuss many aspects of Malagasy life including some politics. We learned a lot about the culture and also about the political life, which is far less glamorous than what is often depicted in the media. Despite hard lives and corruption, the people we met always had smiles on their faces and were never discouraged. Beyond the diverse landscapes, unique wildlife, and breathtaking flora, we had a wonderful human adventure. A long journey awaits us now for the next destination…

[Science #4] Precision Nutrition: Tailoring Your Diet Beyond Hunger and Excess 20

Hunger and dietary excess may seem like opposite ends of the spectrum, yet both can undermine health. Too few calories disrupt essential physiological processes and energy metabolism, while chronic overeating—especially of nutrient-poor foods—can drive metabolic dysfunction, chronic inflammation, and raise the risk of long-term diseases. Ironically, consuming more nutrients than needed often fails to meet the body’s precise biochemical demands, accelerating cellular wear and potentially shortening lifespan. Emerging research suggests that certain calorie-dense foods, when consumed carelessly, may harm healthspan—the number of healthy years lived. Conversely, mindful nutrient intake—or even periods of moderate hunger—can sometimes benefit overall physiology more than habitual overeating. The key lies in recognizing that each individual’s nutritional needs are unique. This is the foundation of Precision Nutrition. **From "One-Size-Fits-All" to Tailored Nutrition** The term “precision” is often associated with medicine, where a treatment is matched to a patient’s genetic profile instead of relying on a standard prescription. That same philosophy is now transforming the way we think about food. Personalized nutrition moves beyond outdated dietary guidelines by using your genetic makeup, lifestyle, and preferences to determine which foods serve your body best. Your DNA might reveal, for example, that you absorb certain vitamins inefficiently, or that specific foods help stabilize your blood sugar more effectively. This approach empowers you to make dietary choices tailored to your biology—not to fleeting trends. **How Does It Work?** It starts with a DNA sample, analyzed for hundreds of tiny genetic variations known as polymorphisms. These influence traits like lactose intolerance, vitamin D absorption, caffeine metabolism, and sensitivity to salt or sugar. Using advanced algorithms, nutrition scientists translate this data into actionable diet strategies. For instance: - If your genes show low omega-3 absorption, your plan might emphasize fatty fish, flaxseed, or targeted supplements. - If you metabolize caffeine slowly, reducing coffee intake could help avoid sleep problems or anxiety. One striking example comes from the GC gene, which affects how well your body raises blood vitamin D levels after supplementation. People with certain GC variants may require more sunlight exposure or higher supplement doses to achieve optimal health. The power of personalized nutrition lies in decoding the relationship between your genes and every bite you take—turning food into a truly personal form of medicine. A comprehensive understanding of each individual’s unique nutritional needs—driven by genetic, metabolic, microbiome, and lifestyle factors—enables the development of personalized dietary interventions that have transformative potential far beyond individual health. Precision nutrition not only enhances quality of life and healthspan but also offers a pathway to optimize resource use and address global challenges such as hunger and malnutrition. Emerging perspectives highlight that precision nutrition, while often associated with high-income countries, is increasingly seen as a vital strategy to democratize health and tailor nutrition recommendations for entire populations, including those in low- and middle-income countries where malnutrition and food insecurity remain urgent issues. By leveraging advanced technologies and data-driven diagnostics, precision nutrition can target specific micronutrient deficiencies, metabolic conditions, and even genetic variations prevalent in different communities. This targeted approach moves beyond generic dietary guidelines, allowing for more effective, culturally relevant, and sustainable interventions that better meet the biochemical and physiological demands of diverse populations.

The Sevenfold Constitution of the Human Being 174

Tupan, 1 d.
Several esoteric traditions believe that the human being is not limited to a single body of flesh and blood, but instead exists as a amalgam of seven interpenetrating bodies, each vibrating at a distinct frequency and corresponding to a unique level of consciousness. This constitution in layers forms a bridge between the material and the divine, mapping the soul’s descent into matter and its potential ascent back to the source. The physical body is the most tangible and material of the seven. It serves as the vessel through which the soul experiences the physical world, bound by the laws of biology, space, and time. It is composed of flesh, bone, and matter, but it does not exist in isolation. Its vitality is sustained by subtle forces, and without these, it would be inert. The physical body is the site of sensation and action, allowing the soul to manifest its will within the temporal realm. The etheric body, also known as the vital or pranic body, underlies and interpenetrates the physical form. It is made of subtle life-energy and functions as the blueprint or energetic matrix that maintains the structure and function of the material body. It is through this body that prana, chi, or life-force flows, animating tissues, regulating health, and forming the auric field sometimes noticed by those with psychic sensitivity. It connects the material to the immaterial, serving as a bridge between body and soul. The astral body governs emotion, desire, and imagination. It is the seat of passions, instincts, and inner images, and it serves as the vehicle for dreams and psychic experiences. This is the body that travels in the dream state or in altered states of consciousness and is central to experiences of astral projection. It has a more fluid consistence than that of the etheric, and it responds instantly to emotional impulses, making it the most volatile and reactive of the subtle bodies. The mental body is the domain of thought, cognition, and reason. It is often divided into two components: the lower mental body, which takes part in concrete thinking, memory, and logic, and the higher mental body, which perceives abstract truths, archetypes, and universal principles. Through the mental body, we develop self-awareness, belief systems, and discernment. It is through the improvement of this body that the ego begins to dissolve, allowing thought to serve truth rather than self-interest. The causal body, or buddhic body, contains the soul’s higher wisdom and accumulated experience. It is the vessel of intuition, compassion, and non-dual perception. This body exists beyond linear time and holds the karmic imprint of previous incarnations—the lessons learned and the spiritual tendencies cultivated. It is the realm of inner guidance and soul purpose, allowing the being to act from harmony rather than reaction, and to notice unity where the lower mind sees separation. The spiritual body, or atmic body, represents the divine will and the soul's alignment with cosmic purpose. It is the seat of spiritual volition—not personal desire, but the execution of the higher law. This is the level of mastery where individual will is surrendered to divine intention, and where the soul becomes a conscious co-creator with the universal intelligence. Those who access this body operate from a plane of deep inner sovereignty and radiant stillness, often manifesting profound spiritual authority. At the highest level lies the monadic body—the pure spark of divinity, the eternal self, the undivided essence from which all the other bodies emanate. The Monad is beyond all form and function, untouched by time, death, or individuality. It is the source of all consciousness within the being and the point of union with the Absolute. Realization of the Monad is the apex of spiritual evolution, where the soul transcends all identities and merges into the infinite. It is the return to the One, the reintegration of the many into the indivisible light of origin. In most human beings, these bodies remain partially dormant or fragmented. The great work of spiritual initiation is to harmonize and awaken each body, gradually purifying the lower vehicles and aligning the consciousness to subtler vibrations. Practices such as ritual, meditation, prayer, alchemy, asceticism, and sacred study serve to align these bodies and bring them under the guidance of the Monad. As one ascends the inner planes, perception shifts from the senses to symbols, then to pure archetypes, and finally to the formless light of the divine. The path is not linear but spiral—each cycle of refinement bringing the soul closer to its origin and its infinite potential.
