Giyom

May I suggest that you or somebody with the time to spare look into the link Glycine has with calming panic attacks and manic episodes. There is a connection to be made with NMDA receptors, improved sleep, and blood flow. Another interesting topic is it's effect on depersonalization.

Great article by the way!

Looking at this from outside shows me just how much of a bubble LW and the Bay Area is. Are people really surprised about the physical modification and terraforming results? The American public almost looks sane.

I don't mean to pass judgement, but maybe it would be helpful to build connections with people not concerned with space travel and AGI risks. I'm sure it would enlighten both parties.

Many including me honestly don’t care about prolonged old age for many reasons. But exercise has done amazing things for me.

One of the best things you can do to prolong your life is exercise, both muscle-building as well as cardiovascular. This was mentioned in the post, but Id like to stress just how crucial this is for a community most likely to die as a result of heart disease (assuming no species-ending disaster). 

Both muscle mass and endurance have been proven to be hugely beneficial for prolonging lifespan, so hit the gym bare minimum once a week. (Its also great for mental health and improves thinking and productivity)
