I think you get out of life what you put into it. At age 71 I don't have to work. I walk the straight and narrow and life is good. I walk an hour a day and keep my weight down.
I recently went to my daughter's baby shower(baby expected end of March) and there were around 40 guests and mostly they were Phd students or Phder girlfriends of my daughter. Delightful girls and most of them are in medical research.
If you spend quality time raising your children you will be rewarded by having good people around you. Life is for living. You reap what you sow.....
