I just find it interesting that people are so different!
I didn't want to travel, either, for years. It was a moot point when we didn't have any money! I wasn't ever jealous when DH went on business trips to exotic places.
I got more interested in travel when DS #1 went to Italy to study, and haven't looked back since. DH and I are the same kinds of travelers, though. I still have issues with time zones and getting sick from travel, but I deal with it. Some of this is from my birth family, who never went anywhere out of New England.
