RE: When sailing in warm places...
I second Ken's comment concerning skin cancer and a proactive and sensible approach to its prevention. Last year, a skin cancer surgury wiped out my summer vacation traveling. At minimum, I lost a good 6 weeks of windsurfing, even at home. Age has a way of haunting you late in life. Without question, most would be well served by wearing a hat when out and about. Sunscreen products can really make a difference. When I was younger, I wish they had existed.
