I'm 29 and would liked to have started after this lifestyle at about your age. You never know what the future has to offer so do what u want, when u want. Anybody can do these things (no matter the age, the kids, the wife, or ex-wife as it may be for some or most????) its just most don't. Go for it.
I don't have to long before I'm finnaly out there.
Good luck and just go for it.
