Nope. I never had asthma as a kid or anything ... just very slowly, starting in my late teens, I began noticing those symptoms. They started very gradually ... it was YEARS before I reached the point where I would have to get off the bicycle part way through a ride because I couldn't breathe anymore (it feels like your lungs have closed). In fact before then, I just ignored the symptoms ... but after being unable to breathe on rides 2 or 3 times, I got a bit worried and finally went to see my Dr.
I'll also add that it has reached a point with me that stress will set it off ... particularly public speaking in my case. I got up to speak in two of my classes and spent the whole time during both speeches gasping for air. In the second speech I felt like I was going to faint because I couldn't inhale. My fellow students were writing little evaluations of me, and a few of them mentioned that it looked like I was struggling to breathe ... well, yes I was!
