Asthma is a killer if you cannot control it. It attacks when certain allergens are around the person who got it, in some cases . Some have had it since they were young because they were inherited and some suffer later in life. Either way there is one way to get rid of it (aside from being miraculously healed).
The reason asthma attacks is because of the weak immune system. Strengthen the immune system and you will less likely have an attack. How? Exercise! The reason doctors recommend swimming, most of the time, is because of the exercise you can get out of it, at the same time enjoying the water. And when you are finally healed you can now enjoy the wind spinner on your garden without having to worry that your asthma will attack due to pollen.
I have asthma and started to record my battle/journey to getting well. I have your blog in my blogroll. I hope you can reciprocate.
