If it's what you've always wanted to do, GO FOR IT. Time is going to pass you by regardless, don't worry about how old you are. Get yourself a good support system so that you can do well in school and everything will work out fine. I'm 33 and will be 34 by the time I start the program, 36 when I'm done. It's all good. I'm gonna be that age regardless of what I do in life, I'd rather be that age and BE in the career I want! Good luck to you!
