I took an online personality test to see what kind of a man I am, and it turns out that I am an INTP - "Engineer!
"INTPs are logical, individualistic, reserved, and very curious individuals. They focus on ideas, theories and the explanation of how things work. They are especially adept at discussions and debate. They have the ability to focus intently on a subject. They appreciate and respect intelligence in others" - is what the site says about my (supposedly) personality. They gave me a chart, too!
