Interesting theory on asthma. I also wouldn&#x27;t be surprised if it was one of those things that just gets diagnosed a lot more than in the past. For example I&#x27;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&#x27;m guessing in the past it just wouldn&#x27;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.
