I'm only 34 but have twice sold everything I owned to go on big tours that my partner dreamed of, the first one was only meant for 1 year but turned into a four year "thing".
I will be honest and say it has been hard settling back in and and finding a good job again, but I now only live to save for the next big trip.
I believe in one corny saying "Carma is a *****" always try and treat other's how you like to be treated and eventually you will always land back on your feet.
Go for it ;-)
