<s>[INST] Could I have avoided getting asthma if I had taken better care of myself in the past? [/INST] 
No. Nothing you did caused you to have asthma. No one knows what causes asthma, but more people are developing it. However while you have no power over the fact you have asthma, you have the ability to control the disease. Source: UNC School of Medicine.
