Do you like swimming?
"Like Swimming"? The album by Morphine? I love it if that's what you're asking!
No I meant actually swimming in the pool.
I really only swim in natural ponds (NSP) because I have an autoimmune disease
Sorry to hear that. I also had problems at the start but they have gone away now
Yeah it's rough, I just recently heard there are 80 types of auto immune diseases?
That is crazy. Lol. I never knew that. 
Yeah, your thymus (in your throat of all places) creates basically everything your body needs to stay healthy so if those "T cells" aren't working its bad news bears
What are T cells?
T Cells are lymphocytes (basically just white blood cells)  that work together in cascading fashion to attack foreign particles in the body, T cell = Thymus cell
