Who wants to live to be "old"

Ive just read some article online about bad habits and how it'll come back to bite you on your ass during you old age, they were for the main part generic stuff that anyone who made it through secondary school could tell you such as eat healthy, and exercise etc etc, it got me thinking... why do I want to grow old?

I work with old people and the physical AND mental conditioning is worse than death.
I know some people who're really strict on what they eat, and they work out how much exercise they need to do to work off meals, they dont touch tea or coffee, energy drinks, dont drink alcohol or smoke, or do drugs, topped off with multi-vitamin pills and omega 3 or whatever we're told is good for us. Then I think with air pollution, wars, random murders, road traffic collisions, everything like that, why do we feel the need to abide by certain guidlines and do what "people" tell us.

I guess what I'm getting at is, if you've got a so called "guilty pleasure" ing do it, cause at some point, in an random amount of time you'll be dead could be tomorrow could be 70 years from now. life is about luck, being in the right place at the right time, but most of all having a good time, not dedicating your life looking after a body you're just renting.
