Advice from Warren Ellis if you’re attending Comic-Con, from his excellent weekly email newsletter, Orbital Operations:

If you’re going to San Diego, buy hand sanitiser, gallons of it, and some one-a-day multivitamin bombs, and lots of water. Don’t eat sugar. Carry loperamide and ibuprofen. User antiperspirant deodorant and pack more underwear than you think you’ll need. Avoid skin in all forms. Denounce the sun. Wear shades to prevent eye contact. Respect the fursona. Store your fluids. Go home. Sit in the corner of the room. Think about what you’ve done.

This seems like good advice for any conference.

And, indeed, for life.
