We could use a thread where people can ask questions about anything and be confused by the answers of those who's brains are clogged by grease.

Here goes, do polar bears sleep, if so how can a polar bear swim for 9 days ?

Scientists track polar bear's nine-day swim
Posted 26 minutes ago

American scientists working in the Arctic have recorded what they believe is the longest swim by a polar bear.

They fitted a female bear with a radio collar and then tracked her as she swam, non-stop, for nine days.

She covered nearly 700 kilometres northwards from Alaska in icy waters, and then walked a further 1,600 kilometres.

The scientists say that as global warming causes more sea-ice to melt, polar bears have to swim greater distances in search of food.

I've just put a litre of clarifier in my swimming pool, so I think I can help.

The polar bear doesn't need to sleep every day, just when it's tired.

From what I can gather they will seek out a block of ice and sleep on that or wood or land but they can't not sleep for days at a time.
