Does that "fact" hold up when you control for body mass and fat/muscle ratio? Because I suspect in reality this only means that we should send smaller people with fewer muscles into space. Life expectancy for example does not correlate with gender anymore once you account for body size.
- Knufen 4y agoThat sounds very interesting, so you have a source for that? I could not find anything on Google searching for "life expectancy, gender and size".
- sigmoid10 4y agoI believe David Sinclair talks about this in detail in his book "Lifespan: Why we age" Personally, I see this is less as a real research discovery and more like a cautionary tale on the pitfalls of statistics and the need for multivariate regressions with control variables.
- im3w1l 4y agoThat's an absolutely fascinating aside right there. Gonna have to look into that one.
- CobaltFire 4y agoThis is an excellent point, and likely one of the main drivers. How much that muscle mass means for the given mission is a separate, but relevant factor.
