Man, it’s so great to have persons (of all genders and) of all more or less crazy religious sects represented here today. WHAT A CROWD! WHAT A CROWD! The answer to a headache, according to one well known sect is not an aspirin and call me in the morning, but, of course, Jesus!
The answer to a headache, like any other condition, is to remove the cause.
An aspirin can cost you your life under some conditions, and you have no way of knowing as you open the bottle, if that will be your last aspirin.
