Musth affects them in so many different ways. You'll get one that behaves iself even when in full musth and then another that is an absolute sod - but I've personally found it good advice to always remember that any Elephant can change it's mind very quickly. For example it can start what begins as a mock charge and they change their mind half way and it suddenly becomes a real one. Adolescent bulls seem to be especially unpredictable - bit like humans really!!!

Cows are even worse and I NEVER take chances with them.....

All that said, most people only ever make one mistake with Elephants. After that you're dead. - A good friend of mine died that way just last year - and she'd forgotten more about Elephant behaviour than I've ever learnt.......but in fairness she got a little too casual and I'm sure that if she were here now, she'd be the first to agree it was a case of death by stupidity.....
