MGTOW and women who say “they’ll never settle”, what do you plan on doing after 45?

One thing that I absolutely believe, is that people nowadays have way too much instant gratification and they don’t think long term. A lot of women will say “I’d rather be single forever than settle”. It’s very easy to say this when you’re 25, young, having fun, etc. However, 45-80 is a long time to spend alone. This doesn’t just apply to these women though, it also applies to MGTOW. They say that they’ll avoid marriage forever. There is nothing wrong with either sex not wanting to marry, but what is your plan after 45? How will you avoid being lonely, especially when you’re on your deathbed?

Edit: women, I’d love to hear your answers as well. There is no “Question” flair. Only “Question for men” and “Question for women”.
