I'm also having the same thing...usually bad smells though. This morning, I had a client come into a small office with very bad BO.... I am thanking everything he didn't want to fill in a form but take it home as I couldn't have stayed with him for the 30 mins it takes to fill out!!!
Drove past a fertiliser plant on the weekend and I was driving and gaged... DH states - do you want to stop!!!!! WTF! why I want to get out of here not stay around it!!!! He then gets it - opps he says!
