[Rosie] Time spent watching overloaded cranes falling over or trucks drive under an overhead obstruction with the bed raised is not deducted form one's life span. In fact, I encourage such behaviour if only to counter those times spent trying to get a human being to intervene 'twixt you and the government (eg to sell you a new road tax disc) after which one tends to sag against the nearest bar and utter such truisms as "there's four hours I'll never get back".
(Stevie) Is there any life deduction for watching leopards strangle warthogs prior to enjoying a tasty meal or watching hyenas ripping chunks out of a buffalo which only gives up when a considerable part of its inside has been removed. Incidentally, the word warthog looks Welsh to me and I always mutter it to myself as if it were. After all there is a genuine Welsh word arthog (short open "a", lightly trilled "r", "th" as in English) meaning bear-like and with the same figurative meaning as in English, i.e. bad-tempered. The plural of warthog would probably be warthogion though warthogoedd or warthogydd are possibilities. It's unlikely to be regular (warthogau).
