Back when Civil War veterans in the United States married girls between the ages of 13 to 15 and they were in their 80s and 90s. This was a financial arrangement to allow the girls to get the veterans pensions for the rest of their lives. As you may well know, a double-edged blade cuts both ways. My mother worked as a Visiting Homemaker back in the 1970s as one of the first in Jersey City. The job was to help elderly women who lived alone to keep the house clean, cook meals and other things you need help with do to old age preventing you from doing any longer. One of these elderly ladies was a Civil War bride who married an 83 year old vetron when she was 15 and he passed 3 years later. Like most of these girls she never had children or remarried because of the stigma of being a, "Graverobber'. We all go through biological changes in our lives every 7 to 10 years. This our lot. In you're 40s you'll get the itch that comes with the middle age change. If you don't have a way to deal with it you'll most likely spaz. If you don't have a solid relationship where your partner will scratch that itch then you'll probably be like the horndogs who cheat on their partners and spouse on dating sites. In your 50s you'll need a companion because you want to get out and about to do things because it's the last real chance you'll be able to. In your 60s you want a bestfriend and your 70s you'll need a nurse. The rule of thumb is aman being within 4 years older then the woman is best, a man being within 8 years older then a women will work and a man being within 12 years older then a woman is the limit. So, take advice from your dear old uncle Gregg if you want. Think clearly and honestly about things like age. You may not like it if you married a man to old to do certain things with because of decrepitude.
