Thank you Mike. The photo sure helps us to see the difference!
I remember once cleaning the leaves out of our swimming pool during a cool fall day... I slipped and fell into the deep end of the pool. The cold water hit me so hard that it knocked the breath out of me. If my husband hadn't been right there to help me, I might have drown.
When I think of people falling from a cruise ship or boat, etc. into cool water I always remember how I felt...the shock! It's amazing when someone survives.
