Same, man, same. I go two years without an asthma attack, including strenuous labor, full-out sprints, and walking an entire marathon doing circles around my campus (long story), but then I try to climb 4 flights of stairs after my ship’s monthly safety meeting and suddenly my pulse oxygen is less than 80% (most doctors recommend an inhaler or nebulizer for asthma attacks that hit 97 or 98%).
