I can't wait until I'm 40, the kids will be out of the house (or close to) and I'm going to travel! Kid's are friggin expensive, good thing I love em so much!
I figure if I start traveling the world at 40, that should give me another good 40 years to see everything. When I'm too old to be shlogging through jungles and climbing mountains they can wheel me onto a cruise ship. Preferrably one with cute waiters.
