• Advice for healthy aging and the importance of purpose in later life

Top 3 Quotes:

• “What is good for a single individual’s health may not necessarily be good for society or humankind in the long term.”
• “We have become so out of touch with our own nature as human beings because we currently live in environments so dramatically different than those in which we evolved.”
• “The only real way to correct the situation is to allow natural selection to come back—and no one is seriously suggesting that, for obvious ethical reasons.”
