I travel a lot throughout Asia and across the Pacific for work, so here we go.

Staying healthy: I try not to eat too much junk food when I travel, especially the candy and stuff in the airline lounges. I also avoid the temptations of unlimited free booze and limit myself both on the ground and in the air. I try to walk around a lot to get to where I need to go, too. My travel over the last year has at least doubled but I haven't really needed to do much else to stay reasonably healthy.

Staying sane: I love travel, so it's no problem for me. I actually have issues when I'm not going somewhere.

Keeping in touch with family/etc.: Ha!

Travel necessities: For me, a laptop, a couple of books and a music player is all I need to make travel easy.
