you dont end up with the headaches and generally feeling unwell as you do with petrol.
I'm generally very intolerant of any pollutants- I virtually come out in a rash if someone lights up a fag next to me, and keep a safe distance from anyone wearing overpowering perfumes. However, have to say I've never noticed any ill effects from petrol fumes, which must be there (?)..... Although its carcinogenic, I also find the smell of diesel and many mineral oils not unpleasant, even mildly attractive. Must be a personal thing, we all have varying sensitivities to different stimuli.
Always said if I launched a gentleman's fragrance it would have mellow undertones of moss, sawdust, beer and wet dog. (just like me).
