re: Older parents- how have your kids turned out?

Two boys 2 1/2 years apart. Oldest has a 4.0 through his first year of pharmacy school while being a distance track athlete with year round training. The other just graduated high school early with no desire to go to college but a strong desire to get rich quick. Two completely different personalities and work ethics but overall good kids as far as staying out of trouble and avoiding drugs. Youngest has been much more of a challenge as he has issues with authority.
