Depends upon the person, how "flexible" you and what your skills are.
Go now and enjoy, as long as you're young free and single get on with it.
Some trades are in demand, others less so.
I'm 40 and finding everso less likely that it'll happen again in the same way.
If you're hankering after a change you owe it to yourself to go-do. Else you'll for ever wonder what your lot would really have been like.
