I feel this very strongly over the past couple of years. As always, hackernews is full of extremely smart, well read people so I'd really appreciate any good reading material on this so I can better understand it. Tips are appreciated as well (healthy diet and regular exercise, good extended blood labs (think like Function health), good consistent sleeep habits).
