How has it affected you ? my strong smell sense has resulted in having to change jobs in the past, and more recently may have to consider a new church, all because i seem to smell things other people don't. The smell is there and i can locate the source, but it's just not strong enough for others to smell iyswim. It's very difficult explaining it to people as i've had people say i'm being 'silly' or 'unkind', they just don't understand it's a real problem.
I also associate some smells with a colour, for instance a rotting flesh smell would be green or yellow, a pleasant floral smell would usually be lilac etc. Just wondered wether there were others here.
