Education is not just for the young and neither is pursuing your goals, no matter what they might be or what your age. I’ve put several links about inspirational elderly people at the bottom of the page for your enjoyment.
I don’t remember where I heard this story, but it goes something like this: A 70 year old man was in college and his 20 year old classmates were asking him questions about why he would want to start college at such an advanced age. One of the youths asked him if he knew he’d be 74 years old when he graduated. The elderly man looked his classmate in the face and said, “Son, I’m going to be 74 years old anyway.”
