He must be about 90 if he is your father-in-law, which isn't what I would call newish.

"On your deathbed, you'll regret the things you never got around to."
"On your deathbed, you'll regret the things you never got around to" (and you will continue to regret then for ever after, even unto eternity.)
That is really the most ridiculous expression that I have ever come across. Can you really picture yourself lying there on your deathbed, thinking of all the things you have not done and being even remotely concerned about them. And even if you were to... would it really matter?

Rudi, I totally agree with you in the sense that we cannot put experiences "in the bank" and go back and re-enjoy them later. It's like people saying they want to do something "while they still can." To me ...well, if you cannot do them later well, sobeit. You will be in a different place in your life. Travel expereinces are not like cans of beans that you can stock the pantry with and live on later. Memories don't go very far in terms of increasing one's enjoyment of life.
In fact, it always strikes me as exceedingly pathetic when you do come on someone who persists in re-living their glory days instead of living their current days. I am absolutely certain the day will come eventually when I no longer have the stamina for international travel. I expect a day will come when I simply realize it's no longer what I want to do. So then I will do other things. I love playing music so maybe I'll finally stick around long enough to get really good and start an oldies rock/blues band. Or I'll finally have time to learn how to do all things I've always wanted to do well - paint, throw pots, write a novel.
Who knows, but what I am understanding about life is that it is important to live in every moment, exactly as it presents itlself.
All that said, I do find that my greatest highs come about when I jump out of my comfort zone and do something that that I fear I might regret - but never have so far. I think THAT is what the quote refers to. But you are right, I am not going to lie on my deathbed enumerating the trips I did or did not take. I suspect the thoughts in my head - if I see the end coming will likely be more about the people in my life and have I done what I needed to in respect to them.

The doctor says grandpa is slipping away quickly now, a short while
and his time will have passed. What? What's that he's mumbling about
to himself. Go listen. Whats he saying?
You won't believe it! He's actually grousing to himself about the time
he had a chance to lay grandmother's sister and passed it up!
