"For four rough days I had sailed due east from Samoa in a rusty old vessel called the Manua Tele which I had chartered in Pago Pago. Our destination was Suvarov atoll, a tiny group of islets in a coral reef normally uninhabited but where, it was said, a white man had lived alone for five years.
When I awoke on the fifth morning, the swell had gone, the Manua Tele’s engines were still, and the old tub was rocking gently at anchor. I donned a pair of shorts, picked up a tin of beer and some bananas and went on deck.
Ahead of us the reef thrashed the water in a line stretching for miles; beyond it, drenched in sun, was man’s most elusive dream, a coral island."
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
