Hi Chinmayi,
ReplyDeleteWhen we tickle ourselves, our mind knows in advance that is supposed to happen. So we develop some sort of a defence to counter the effect of the tickle.
When somebody else tickles us suddenly our body is not prepared for that change of state.
Even if you hit yourself (not too hard) it pains lesser than when some body else hits you suddenly.

Hi Shreepreeth,
ReplyDeleteGenerally what happens is that after drowning and floating for a day or so, a body will sink for a few days until gases due to decomposition make it float again. Part of this also depends on the temperature of the water. The warmer the water, the quicker this process happens.
