Again it's a personal thing, some things I found uproarious when younger now only raise a wry grin, other things have me laughing out loud & in tears. I'd say that your aspects change & you perceive different levels of humour, just look at some of the "Kids films" Shrek, Ice age, so many levels, kids enjoy the visual & slapstick so do the adults , but there's innuendo & double intendre that go straight over the kids but has the adults in pleats.
So yes, I think you humour changes. As to does it help? Sometimes, but it depends on how deep you dropped yourself in it whether humour alone will get you out of it, as folk are wont to say "Oh I'm always in the she-ite, its just that the depth varies !"
