I’m 6’5 so yes. Sometimes I can. Not always though.

No. I once tried using a pool whose "shallow" end was well out my depth, so probably two metres.

Usually not lol

Deep ends how deep. Too much I can do it without breathing.

yup.
just cran't breathe

Yes, but the water would be well over my head

Sure, as long as there’s no water or anything in it

In kids pool 3ft hell yeeeHhhhh!!!

It depends on how deep the deep end is but usually, no.

if I hold my breath yeah

No
