Is there anyway to become dumber?

Sometimes I feel too smart to have friends, they consider me weird for my eccentricities. I just want to live and die, no history I don't want to challege the greats like Einstein this world is better left in the dark, we just like to kill people why should I contribute to that. People will always be selfish because we are organisms and we have needs. Only when we have no needs, in death can we truly be at peace. I just want to live peacefully and sleep my life out. Ironic I now sound selfish because I won't contribute my intelligence to the world. Anything I can do except take drugs or just try to act more dumb? I tried acting more dumb but I still have strange thoughts on the universe and I am almost always out of where I am physically because I am such a deep thinker, profound I know but I am def not conceited, just looking for a solution for a medical problem?
