Torrential rains recently killed a bunch of people in China.  And a few weeks ago, a few people died in the US because of a heat wave.  I'm always surprised by things like this because I have trouble imagining how people die in cases of relatively standard weather patterns and natural events.  It makes sense when people die in tornadoes, floods, and earthquakes since these events are typically unexpected and fairly violent.  But rain?  Even if it's a lot, can't you just make sure you keep your head above water?  (Although in the case with China, the rain caused pretty severe flooding, which explains the number of deaths.)  And with heat, when exactly does the dying happen?  Can't you find some shade or turn on a fan?  I doubt I would survive a tsunami, but I routinely survive both rain and heat. #nature
