Interesting theory on asthma. I also wouldn't be surprised if it was one of those things that just gets diagnosed a lot more than in the past. For example I've been diagnosed since I was around 10 but despite it being quite bad when I exercise I rarely use medication and have never had an attack. I get out of breath much more easily than a regular person but I'm guessing in the past it just wouldn't have been diagnosed as there was really no episode that led to the diagnosis other than the doctor measuring the strength of my breath during a routine visit I believe.
