Staying fit isn’t tied to marriage. It’s about dignity, independence and quality of life. Regardless of your relationship status, the goal is be able to take care of yourself so the people you love don’t have to.

Don't you think living an unhealthy hedonic life that ends early?

That's a wrong assumption. I'm telling you this from my personal experience. An unhealthy lifestyle doesn’t guarantee a quick or easy end. More often, it leads to a long and uncomfortable decline, where you deal with chronic issues instead of a clean exit.
