Why is time more precious after 60?
In my life, time was more precious when the kids were babies/toddlers/little ones. I cycled then, too - altho a bit less.
Then the cycling got better.
One makes one's own priorities.
Live it, don't just do it.
Then even better
I believe you chose your reality. Grab the priorities while you can. Enjoyment becomes more precious after 60.
