Aha. I wouldn't choose "feel no pain" even if it seems to be a pleasant condition to be in. That's because pain is an integral part of existence... without it, there wouldn't be the absence of pain. Without the absence of pain, there wouldn't be comfort and joy.
But that's too much to sweat about. Ye, I also choose walking in the rain. Although, recalling my near-death experiences with hypothermia while walking in the rain up Mt. Pulag... hmmm... ye... it depends.
