I haven't bothered reading all the replies but I was the same age as you when I decided to join. It's not too late. Applied at 26, initial app rejected, told to wait a year and do some stuff to make me "more rounded", which I did. Re-applied, great success, started at Halton 2 weeks before my 27th birthday. Had a ball since - 2 tours on rotary and now on my second fixed wing tour. Just go for it and enjoy it, leave the cynical bollocks for later. The flying will be awesome and the mates of all ages you will meet and share experiences are true mates for life.
