Personally, well, I am in my late 50s, and would love to have a young lady who would like some children, so she must be of legal age, at the very least, but 20s or 30s if YaHWeH opens that door, great; if not, great either way great. I have a friend with 3 wives. When he was 53, he married an 18-year-old. I asked him what are the pros and cons of marrying one so young? He said, "Only one con," he said, "at first I sometimes felt like a parent, not all the time, just sometimes." She's well into her 20s now. If you are an "old guy," make sure it's YaHWeH's will. Don't let the little guy lead.
