Don't Walk in Tall Grass or Stick Your Hand in Covered Places - Thailand has more than its fair share of poisonous snakes. Don't walk in tall grass and don't put your hand anywhere that's covered - that includes holes in the ground, covered bowls, swimming pool drains - literally anywhere a snake might hide. A couple of hundred people every year die of snake bites in Thailand and many thousands have serious injuries. Look where you're walking when you walk and watch where you put your hands, so nothing comes out of the darkness and nabs you.
