Allergies are weird things. I have perenial allergic rhinitis (Hay fever all year round!) probably due to dust. I think it is more likely to be pollution based but until I can move out of the city I will not know. I am 58 years old and was fine until I was around 25 when I developed Asthma.

Oddest allergy I have though is to smoked mackeral. Any other mackeral is fine. Any other smoked fish is fine. But smoked mackeral has me doubled up with stomach cramps and unable to function for about 4 hours. Maybe it is a Gnome thing!
