Do you have asthma and exercise regularly? I need some tips!

Wear a mask in the cold weather or you won't get too far.
Stay out of moldy gyms and locker rooms.
Take lessons on a horn of some sort--it worked for Pete Fountain
I met someone who got an I-Robot Rumba auto vacuum and swears it cured her asthma.
I cured mine by putting anti-fungal powder in my shoes regularly, and taking a lot of garlic pills, and hawthorn to increase my O2 uptake.
