Three minutes and the cold sea will takeaway your life the body temp will disappear on the waters at this time of year you would not have much chance of survival even if you avoid the heart attack on first entering those grey depths. The Sea knew what it was doing when she threw us up onto the shore to crawl away into the jungle and take our chances when our legs unfurled and we finally stood upright carrying our evolution with us. I cannot but help wonder if the sea gave us up to turn around one day and take pity on her like sons and daughters towards their ageing parent.
