There's always the possibility of being drowned in poo by giant sloths. I seem to recall.

I've not been in many caves. Not sure I can be arsed with the wriggly, hard-hatted, crawly type ones, seems like a lot of effort. But I quite like ones you can get into without too much bending down (bad back you know).

And Paviland is still the most exciting place I've ever been.
