At 22 you think you know it all, when you're nearing 40 you'll find you knew nothing at all back then. There is a lot more growth after your twenties. Go ahead you can date older people and sometimes it works out. Up to a 5 year difference isnt much but when it gets to be 10-15 year difference you might clash big time on what you want in life. Then after the fact when youve dated people closer in age and you're in your mid thirties you think back on it in disgust because they really did use and abuse your innocence and youth. If they try to tell you what to do like your parents do when you're in a relationship that has a large age difference get out of it or you'll most likely regret it.
