When I discovered how old they were, it seems they were including all their experience from the tender age of 7 (I seem to recall). As the discussion concerned technical aspects of taking risks etc, it was pretty obvious the length of experience quoted was just meant to show me that said person had enough experience for me to show some respect towards them. Said person was clearly a trained cave leader, so I'm not sure what the years of experience figure was really meant to prove. I think it's pointless to include years of caving before a certain age has been reached. I would venture to suggest 16.
Well the 9 years above, of my own continuous but intervalled experience, include at least 2 years between the age of 11 and 16. As a mine enthusiast I would have thought you of all people would realise that much experience can be gained below the age of 16... I am sure there are many OAP coal miners out there even now thinking ..."I remember when"...!
I think perhaps 7 years old is a little over enthusiastic but certainly from the moment your scout-leader/parent/trainer stops checking your knots, harness and rigging ...why not include that period of time. The couple of years between 11 and 16 involved some of the most rigorous caving I've done, I have never done SRT but there were certainly many long ladder climbs in that period... wet and muddy with wellies on... personally I'm more than happy to include my pre-16 experience. By 11 years old I could steer and order others on the sailing of an enterprise (God, I loath sailing), orienteer as well as I can now and arrange my own climbing harness, 'check my knot and check my partner for abseil or top rope' very competently.
I sometimes think people forget that before all this people used to die at 30! Imagine if you didn't include your pre-16 experience back then.
I once had a friend pass on a CV, for some advice, to the head of an industrial chemical firm (because they were good pals). The helpful pencil comments included, "How can you say you are innovative in your working life - it's so blasé for someone so young!". I was 22. So apparently us young folk can't improvise or be imaginative either!
I know a 15yr old that climbs 7b sport! Sorry but whilst there are certain reproductive/personal aspects of life where I would batter someone to death for touching my kid (if I had one)... I would still, despite being an overbearing mother no-doubt, consider their experiences as valid as mine. Kids learn not to touch a hot stove soon enough!
