Our bodies are not perfect. Far from it. In fact, they have serious flaws. Most importantly, its greatest flaw is that one day it will die. Over time evolution decided it preferred that humans die so those younger, stronger kids can take over eating, mating, etc.
You and I may not be OK with dying. If we pour effort or money into anything, it should be in trying to keep ourselves living longer. Live long and forever, if at all possible. Gosh, I think I'll have to dedicate my life to learning about longevity.
Most of all, longevity of the brain. The way I se it, if my brain goes, I pretty much am done too. Gotta study longevity, brain health, etc.
