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.
