Lol broke off is kind of a colloquial term, continental plates drift around all the time, it's not unusual for land masses to divide and part ways from each other!

I thought we break bones because we fall.

Well we do =P but with some elderly people who 'just fall', it could be the other way round. Of course, for some people they fall because algae made them sick =P

Still haven't seen jumanji yet, don't spoil it!
