I am older now, and I don't believe you care less what people think as you get older, that is a cliche a lot of people use. If someone physically or verbally attacks you, because you are older, it is supposed to sting less? i don't buy that for a second. If someone targets you at age 20 or tries to harm you or your family, why would that hurt any less at age 60? I just think personally, the only way i really care less what people think is just me having a generally passive "whatever" kind of apathetic attitude about life as I get older.
Some old people deserve respect, and some are jerks, it all depends on the person. If a Nazi is 80 years old, should we all respect them and be cordial because old people deserve respect? If an 80 year old is a jerk, should we feel obligated to show them respect?
One thing about old people that Chris Rock did a bit about is "You don't want to be the old guy at the club. He isn't really old, just too old to be at a club." So if you see guys in their 50's or 60's well past a mid-life crisis and they are at a hip nightclub hitting on 20-somethings, that looks totally out of place. Not wrong exactly but odd.
I think me as a guy, i unfortunately do look at marriage and children as a financial weight that i could not handle. I also am sad about the fact i probably will never get married and have kids, but in logical terms I do see money as a huge factor. I had chances as some women were crazy about me in the past, I simply felt that they wanted to suffocate me and spend every minute with me, so i ended those flings. The way i see it, I would rather be alone and go to sports games or movies and relax in peace rather than talk for 12 hours a day and sit in a room with someone on top of me without room to even breathe.
Women with barely any money i think still will want children because it is just a biological need so they feel complete. Men even with money, often will make a logical decision to not get married for financial reasons, which is sad on some level and smart in a way also.
