Aging is a whole-person thing
Felipe Salech is a geriatrician and geroscientist at the Universidad de Chile, and one of two Felipes who hosted the Chilean leg of the quest (the other is Felipe Court, a brain-ageing scientist — interviewed the same day). Salech co-founded Salud For Life and is a researcher at the GERO ageing centre in Santiago.
His starting point is a reframe. Gerontology is not only biology or medicine — it is the whole-person, whole-society study of ageing, reaching into economics and social science, because a human being is not divided into a biological part and an economic part. We age as one whole thing.
And ageing, he argues, is a whole-life process that must be addressed far earlier than the geriatric clinic. This is not theory for him: his group has biological data showing that children who grow up with obesity age faster — measured with biological clocks. The idea that you should tackle ageing while young now has hard evidence behind it.
The most useful thing he says is about how to actually motivate people — and it applies to everyone, not just the old. Nobody wants to see a geriatrician, because it is a symbol of getting old. So he does not sell youth; he sells a goal: independence. And to be independent you need two things, which frame his whole practice: a brain that can make your decisions, and a body that can carry them out.
Obesity, he points out, attacks both ends of that at once — raising the risk of dementia and stroke on the brain side, and infiltrating and inflaming the muscles on the body side, in a vicious cycle. Keep both working, for as long as possible, and you have kept the thing that actually matters.
