I really don't have anything bad to say about people who are set on aging and dying - I just think that most of them haven't really thought it through, at least not to the point of understanding just how much personal suffering is going to be involved. (Which is why the old age simulation suit is such a great idea). We humans are just not all that well endowed when it comes to empathy and planning ahead. If we were, you can be sure that age-related degeneration and death would be solved problems already.
Regardless, there are still those folks who have thought it through and decided that aging and dying is for them. I'm certainly not one to argue against the value of freedom and personal choice, even if I'm quite sure that most of these people will make glad use of cures for age-related degeneration and death further down the line, despite having done nothing to help bring about this bright future of medicine.
No, the people I have a real problem with are those who seem set on forcing others to suffer and die. Personal acceptance of values that denigrate science and medicine and glorify suffering and death is one thing, but setting out to force the consequences of these views on others is nothing less than horrific.
