This thread reminds me of a question in an advice column I read years ago. The question was from a woman who wanted to go back to college to become a teacher, she was in her 40's, and she was bemoaning the fact that when she was finished with college she would be 48. The advice columnists answer was - 'and how old will you be if you don't go to college'. That has always stuck with me. I say - go for it!
