Nigel,

I am thinking of taking up archery as a hobby, and I require you to put an apple on your head so I can have a go at sharpshooting. As I have no practice - I last did archery at school in 1978 - I am aware of the risks if I am an inch or two out with my aim. But you need to fully accept those risks.

No ifs, no butts (pun intended).
