Reason I'm bringing this up is because with Chris Borland of the 49'ers announcing part of his choice for retirement was due in part because he saw that playing a full career in the NFL could shorten his life expectancy by 15-20 years.
I think if I had the choice of doing something I loved and getting paid very well for it, but it means I might live 15 years less then the average life expectancy, I think I'd go with it. this is of course not an option for me and purely hypothetical. but hey living a life that is shorter but brighter, would mean more then a long and uneventful existence.
I might have a bit of an unorthodox view on my own personal life though. Because, if someone told me I'd be dead in 5-10 years, I don't think I'd be upset. The only thing that will change would be what I'd be doing with my time left. Instead of working a poo job because it has good pay/benefits and retirement, I may live my life in a totally different way and pursue stuff that I actually enjoy doing more with the time i have left.
