Running Again

I went running last night for the first time in 3 years, 11 months and 6 days (approximately). I was afraid my legs would be cramped up and sore today, and while I can tell I went running, they're actually doing pretty good. I think this is because I've been doing Yoga, so my muscles are used to being expected to do impossible things.

However, my heart and my lungs were traumatized. I felt like I was trying to breath into two little apricots, I couldn't fill my lungs with enough air to keep me going. I feel like I must continue to run or my lungs will get smaller and smaller until I can't breathe in at all. And that would be bad.
