Longevity Primer

Laura Deming runs the $26 million Longevity Fund – a VC firm dedicated to funding early-stage companies with a high-potential for increasing human lifespans.

Her blog has an interesting primer on longevity and the science behind increasing human lifespans. It’s filled with all kinds of well-referenced facts about things that affect our aging and ability to lead long lives.

10 years ago, one of the first projects I worked on was trying to understand a weird fact about reproduction in worms. If you take little worms and get rid of their gonads (I know, it’s weird), they live ~60% longer than normal. But this only works if you get rid of the stuff inside (sperm/eggs – these worms are hermaphrodites, which means they carry around both). If you get rid of the whole thing, lifespan goes back to normal.

Don’t miss the 95 things that make mice live longer and 70 drugs in the clinic that might make people live longer sections.

What Is Old?

Having recently turned 40, the question “At what point does a person get ‘old’?” holds some interest for me. I like this idea from the above link, “A person becomes old when his mind is more occupied by memories than aspirations”. I like this because it doesn’t stigmatize being old and at the same time allows for becoming old to be a choice. But I think the more honest answer is “One becomes old the minute one is aware of how they are perceived by those who are young.” Old is not a state of mind – at least not your mind – old is inflicted on you by youth.
