And here’s another clip, his Marriage Tips from another interview:
Divorces run in families. If you didn’t know marriages when you were growing up, find people who are married and find out how they do it.
Arguments are a natural part of any relationship, but cruelty is not. Above all, happily married partners see each other as allies, not as adversaries.
To go without sex is to endanger the relationship. It’s very easy to build up an incest taboo in a marriage. If you go without sex, your instincts recognize this person as part of the family but cease to recognize the
person as a sex partner. The response can kick in surprisingly quickly – in as little as six weeks. People make a terrible mistake in being angry with their marriage partner and cutting them off sexually as a way of arousing great passion. It used to work in the ninth grade. But it doesn’t work in the ninth decade.
Caressing and contact is always a good thing. The great thing about sex at this age is it ceases to be great, and it becomes funny. It feels good, but you never know what’s going to work and what’s not. Which brings up another trait that long-lasting marriage partners often share: a sense of humor.
Humor is vital, but it is vital to be happy, too. A happy marriage is a marriage between two happy people.
You’re not going to be in love all the time, but if you want to recapture that magic from when you were in love, be loving. Being loving to your partner makes you feel so good about yourself, it doesn’t matter if you’re in love or not. The marriage is making you feel good if you are loving in it.
There’s no point battling age in yourself or in your partner. No one has ever won.
Always keep your pants zipped in public.
