my Brother is a pyromaniac , when we were kids he loved setting fire to things , he was in trouble for it with my mum , and at school, we was in Boy scouts he could light fires with wet wood in the rain with no matches, lighter or petrol ,,after he got his Chemistry and Physics degrees he went on to work on Nuclear weapons for a few years ,,thats big pyromania but he never let one off ,, now he designs engine management systems for the auto industry .Still loves lighting fires though
