I never watched the one year TV series but you made a great post because it had to do with rich people targeting the hero for use as “their personal blood bank” to stay young.
The actor Christopher George was married to the lovely Linda Day George for years. They say men age more slowly with a younger wife. 14 years her senior.
He still died in 1983.
Yes, and they worked a lot together.
