There are several possible causes for headaches.  According to a Chiropractor friend of mine, dehydration is a major cause.  For example, too many Margaritas one night can leave you seriously dehydrated, hung over and with a headache the next day.\nOther causes are stress, allergies, etc. Dr. Hoffman's reference below explains some of these in detail.

When 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.\nWhen somebody else tickles us suddenly our body is not prepared for that change of state.\n\n Even if u hit urself (not too hard) it pains lesser than when some body else hits u suddenly.
Why do we get tickled when somebody tickles us and we don't when we tickle ourselves?
