RE:RE:RE:RE:RE:RE:RE:RE:RE:Leonard Nemoy in 1979It depends on what you find "acceptable". If something is dangerous then you don't want to expose yourself to it. This is dangerous although more so for those of a certain age and with pre-existing medical conditions. And so what? If life expectancy is 80 and you die at 60 does it make it better than someone who is 30? How do you measure somebody's worth? I'll take a 70 year old over many 20 year olds as far as what they contribute to the human condition.
