And a brilliant role model for people who dislike the animal, Homo sapiens.
Attenborough's just lucky to have a had a job he loves for most of his life and good health to go with it. It is a job he has done extremely well so his employers are willing to keep him on. He has brought in cash for his employers so it's worth them making allowances for his age. I dont' believe they don't have to do that.
So, yes, a role model of sorts, but most people aren't as well endowed with his luck (background), his intelligence, and his good health. In that respect he reminds me of Margaret Thatcher, she who believed anyone could pull themselves up by their boot straps and didn't seem to make any allowances for the fact that not everyone was as bright as she was at school and that her family circumstances, though 'humble', were far less humble and insecure that those of many other people.
I'm not ranting aginst what is often called privilege, just pointing out that it makes a difference to one's life chances.
