So is this what you tell yourself to justify sitting in your chair eating doritos and mountain dew while blasting cigs and chugging beers?
What are you even talking about?

1) Worrying about your health is mostly useless and probably won't move the needle much unless you have obvious problems.
2) The United States spends 20% of it's GDP to accomplish nothing. That 1 year of life expectancy gain is probably within the margin of error. Certainly modern healthcare can help at the individual level, but the society is so sick that any gains are washed away by the noise and we spend a truly enormous amount of money to get nowhere.
Our worry costs us a fortune, and generally just doesn't accomplish anything worthwhile.
Saying "if you're healthy you shouldn't worry about your health" is a meaningless thing to say. The point is that most people _do_ have obvious room for some kind of health improvement, and as other commenters have pointed out, if it's not in the clear "this will help me live an additional N years" way, then very likely it is in the "this will make my life suck less as I age" way. Eg; Being able to walk up a flight of stairs without getting deeply winded.
However, would I regret not being fit enough to go for a hike in my 60s? That's another story, and it is one which many do have the ability to intervene on.
Treadmill time as an enabler of other experiences may well be worth keeping, even if the time spent on it doesn't satisfy some imagined "will I think of it on my deathbed as time well spent?" bar. I imagine there are a great many things I won't think about on my deathbed which on their own are unremarkable or even gasp not very fun, but that is of course not a reliable measure of whether something is worth doing.
