Try to avoid getting divorced.

If you get divorced after a 20 year marriage you may find that you have some adapting to do if you start dating again.

You may be surprised that the girls have declined and have become fatter and ruder. You will also need to adapt to technological changes.

You may discover that you have become more jaded, less tolerant, less patient, and more dishonest.

A man may find that he has underestimated the affect of aging. You will have had hair loss, more gray hair, worse teeth, worse eyesight, worse hearing, and wrinkles. You may have scars, have a lower sex drive, be out of shape, and have less energy. Using glasses, hearing aids, and a cane is just not sexy.
