Why do people criticize me?

people sometimes criticize me for going after young hot girls (in their 20's) at first I thought they were jealous but now I'm not sure. I just think to myself if I settle down with a hot 42 year old (rare) then in 20 years she will be 62 and have gray hair, dentures, and those scary huge hoop earrings(the thing that scares me the most) and I haven't slept with a woman in her 40's since high school.
