268: Evo Psych Diet, Retiring Early, Stressed in the Stone Age, Covid Tantrums

In today's episode, Dr. Lisle and Dr. Howk discuss:  1. My question is about how evolutionary psychologists can interpret the species-specific human diet differently. Dr. Lisle supports a plant-based, starch-heavy diet. Meanwhile, Dr. Geoffrey Miller supports a paleo diet (heavy in meat and greens). It seems clear that the majority of calories were gathered, not hunted, which lends weight to the plant-based, starch-heavy type of diet being the standard human diet and the correct one to follow. How can researchers have such different interpretations of human diet? 2. I would love to get the doctors' take on the FIRE movement (Financial Independence Retire Early). Is it just another example of the enlightenment trap? I read "Your Money or Your Life" in my mid-twenties and since then have been saving approximately half of my income. I now have enough to "frugal retire" if I want to. But now I don't have a goal to work towards. I've always wanted to travel and learn foreign languages; so I'm doing that. But I know that if I wasn't taking classes every day I'd be bored out of my mind. Did I just waste the last decade of my life engineering my very own complacency cage? 3. Noways, a lot of people gravitate towards food when they are stressed. What did people do in the Stone Age when they were stressed? Did they fight, did they sleep, did they meditate, did they go on walks, did they talk about it? And what about animals? What do they do when they feel stressed? 4. I was wondering if Jen and Doug have ever talked about the increase in angry violent outbursts on airplanes and other places that has happened in this age of Covid.  There have always been angry outbursts but why have they increased now.  Is it some kind of temper tantrum in reaction to loss of control due to Covid.  Social media is just filled with these incidents.
