I'm actually looking forward to turning 30 this year because people still confuse me with a college kid (I'm 29 and 6 years past my 5 year college sentence) and sometimes even a high school kid. I think it will be fun to convince people that I'm really 30!
If you're having trouble dealing with being old, consider this:
(1) Only 10 years from 40
(2) Only 20 years from 50
(3) Halfway to 60
(4) Almost half your life is over and the older you get the faster times seems to go...
