....Do you know that a shark has to keep swimming 24/7 otherwise it will drown or something?)

Hi Al, that's not quite right.
They can sleep on a sandy sea bed if the current is flowing past their gills.
I saw 3 white tips doing this a few months back whilst scuba diving off Malapascua. This was in the middle of the day as they like to hunt and eat at night.
They doze and you can get up close and lay next to them.
Now, that's a nice thing to see
