"Beer is OK - Remember that it is generally 95% water."
Yeah, that's the excuse the drinkers of Guam like to give. "I need to stay hydrated!" Try inebriated...
Still, they are not as affected by the heat as some of us are.
Our group, the Traditional Seafaring Society built a traditional canoe house last year. Essentially it is an A-Frame roof with no walls. On the hottest day you can find relief in that canoe house. The air sweeps into the shade and the hot air rises into the peak. The roof is thatched with pandanus leaves which is thin and allows the hot air to escape. And judging from how much that group can talk there is plenty of hot air to go around.
