I'm sensitive to all smells. My father is a handyman. He is always using all sorts of industrial solvents, glues, paints etc. Lately, he is painting the boat under the house. However, he must shut all the doors and windows of the house before opening any paint tin. I tolerate smells better outside due to large amount of air. I tolerate smells much less in an enclosed environment (such as the house). I try to avoid prolonged exposure to indoor environments where I cannot control the smell, e.g. shopping centres or air conditioned office buildings with no external opening windows. Once a smell enters the air conditioning, it goes all throughout the building - Sam
