You are always complaining that you are sickly and take it out on exercise. Exercise is fine, but know that the top of your head is very sensitive.

If even a single drop of water falls on it, you will catch a cold that will progress to the flu.

If you are hungry and the sun blazes on it when you walk outdoors, you will develop a migraine headache.

The solutions are to take a hot shower immediately and then take a one-hour nap.
