I work in retirement and its tough to see the older ones with no kids as sometimes they have no one to take care of them and start to get dementia. But having someone to take care of you is no reason to have kids. If I ever did have them I think I am going to stick to one. We both work full time and like having the freedom as you mentioned. My typical day is work, gym, eat/shower, netflix, video games. We go on 3-4 trips a year too. My entire lifestyle would have to change if we were to have children. I do think I am going to have one though in the next few years. 1 kid and a few dogs is good for me. When and if I do have one, he/she is going to be the biggest weather weenie east of the rockies.
