How can I improve this thesis statementStereotyping not only affects behavior, but it can cause mental illnesses, and alter one's perception?

Cause mental illness? I think that's gonna be a tough statement to justify. And, imo, a lot of stereotyping is appropriate. For instance, I always assume that an 80 year old man can't run as fast as a 20 year old. There might me an occasional exception to that, but it's generally true. A lot of our "stereotypes" are.
