In terms of my organization, we classify senior...it's a life course. It is a life course approach to aging. So if we were in Sierra Leone, I don't think any...actually, there are a couple of males who are under the age of 37 here, but all the rest of us would probably be dead. So if you're in Sierra Leone and you're a male, at 37 you are probably considered old. If you're in Japan 70 is considered old, or older. But if I speak to our main representative at the United Nations, Helen Hamlin, who this year turns 87, she would say she's not old.
Governments make an arbitrary benchmark around aging. In Australia, if you're an aboriginal, at 50 you're considered a senior or you're eligible for what someone at 65 would be eligible for.
