I can't mouth-to-lung anymore. I don't know if I've forgotten how or if my lung capacity has just improved that much. When I hit mouth-to-lung devices, it just doesn't feel right no matter how I go about it. It feels like my lungs are pulling in on themselves even when I'm gentle. Too much back-pressure for me. I've been lung-hitting exclusively for the better part of 2 years, though. I also tend to run my airflow wide-open. I guess I've just become accustomed to that deep, relaxed drag. Nothing's quite as satisfying as a nice, dense lung-hit. Breathe in. Breathe out.
