I know a few people  who have been trampled by sheep. If you turn up in their feild, then they assume that youve turned up to feed them so come running towards you, and end up nuzzling you to get you to start dropping food. then not being the brightest animals in the world,  theyll run over the to of you till they realise they cant see you anymore. This tied with their flocking behaviour can leave you with quite a few bruises if you're not aware around them.

watching the new farmhand who hasnt dealt with them before can be quite entertaining.

Any idiot can face a crisis - it's day to day living that wears you out.
