Why I don't sport climb or boulder much

People keep asking me what I think is so bad about sport climbing (and bouldering for that matter). There are of course a massive number of mocking remarks that can be used to rile up an aficionado of any particular climbing discipline and in the past I have often resorted to these rather than a serious attempt to qualify why I don't find sport and bouldering very compelling. A small seed of an idea came to me a while ago however and recently fully blossomed into a realisation of what drives me to trad climb. Risk. Admitting this raises the horrible spectre that I might just be a bit of an adrenaline junkie which isn't an admission I really like making. When trad climbing, every nut or cam has a chance that it will fail and on most routes there are places where the consequences of a fall are either suspected to be serious or known to be serious. When sport climbing or bouldering (highballs excepted), every fall or failure is assumed to have next to no risk and as I feel like there is no penalty for failure, I also find I have little motivation to succeed. Obvious there are many other reasons I like trad but I think this might be the crux of the matter. there, now it is on record :)
