The student tradition here is the go to the harbour wall, strip naked and jump in to the sea.
Every single year someone jumps without checking if the tide is in and breaks one or both legs. One year a lass broke her thigh and bone marrow got in her bloodstream. This killed her.

No not really. But bone marrow does support the production of lymphocytes that are the immune system.
That then reject transplanted livers.

There's a similar one here involving the Bridge of Don.
I also went to University with a seemingly not very good geology student who broke bones injuring himself falling off some rocks believing there to be gold up there. He was on the local news.
