Thinking.

Thinking is very hard on the brain. but it depends on what you think on. for example, if you think about random stuff, it'll come easy to the brain, making it work well later on in the day. if you think about another person, a friend or relative, it may be calm yet serious in which the case would be sickness, then it might be a problem. if you think about the one you like, love, ish or even hate, your brain will seem very confused and complicated. to me all of these are correct in my mind. wather it be random or love, the brain is always working. but i havent been all to clear on the outside yet. the inside is saying one thing while the outside is just looking in.
