You are right Barry. When I was a kid we always ran around during summer
with nothing but swimmers on.......Today at 50 yrs old I suffer....The
occasional skin cancer burnt off with dry ice. ............My advice to all
is to cover up ie. wear a long sleeve shirt, long comfortable cotton slacks
and a BIG hat. As there is nothing else I know of out there, I use 30+ and
have the Australian White Nose.
Regards
John (Tayben)
