I was self employed for 30 years. Decided to take a full time position at 60 (money is about the same). Sometime in the next 3 years, I’ll go to working part time, either back in my own company or at another company. It’s important to do things that challenge the brain as we age but also have time to explore other places, things, interests.
Keep physically fit as much as possible. Although I hike daily, cycle as much as possible and kayak on occasion, all of them will start being less intense as time goes by.
People think they should eat better as we age. Reality is you should have eaten better all along. There is no time when you can get away with eating crappy on an on going basis. There is no time when it’s healthy to drink too much alcohol.
