The weather this morning in the LA valley was 37 degrees, it's now 39, yikes!...damn it's cold...I'll say this though, the Wim Hof breathing technique really does work...I was coming home the other night and forgot to bring a jacket and just had a short leave shirt and pants...I had to walk about 15 minutes to get home...normally I would of been shivering cold as it was 41 degrees at the time, but I did Wim Hof breathing the whole time and eventually I forgot about the cold...it was a nice testament to see what my body could handle, breathing is a powerful tool.
