Brain Aging, Common Sense
Randall Parker uses recent research into the genetics of the aging brain as the starting point for some common sense talk on health, aging and the future of anti-aging medicine: "Probably in 20 or 30 years time we will be able to grow replacements for all the internal organs. ... But the brain is our identity and needs to be repaired, not replaced. ... This makes brain rejuvenation much harder than rejuvenation of the rest of the body. We need to slow brain aging because effective rejuvenation therapies for the brain are going to take longer to develop than rejuvenation therapies for the rest of the body. ... Even if you are very confident that a cure for aging will be found before you die that is not a reason to be complacent about your diet and lifestyle. ... Best to delay the onset of assorted maladies as long as you can."
