Why do old people fall asleep in public so easily?

If we are talking elderly it may matter upon their health condition. Otherwise I would say they are bored of those younger than them

Oxygen issues and young folks sucking it all up by talking too much. ;)

Cause them public folks is really boring.

To block out the youngsters whining.

I’m 27, and I do this.

life is boring. Power naps are also good for you

Though I don't recommend them while driving

All those sleepless night we had with sick kids catches up with you eventually.

Old people sleep a lot, same as old dogs and cats sleep a lot.

80 years worth of Mondays takes its toll!

Perhaps they're tired !! 😴

Being tired as buggery will do it.
