Humans were only "designed" to live until they reproduce and the human lifespan was far, far shorter until the last few hundred years. Just because it's possible to live till 25 and drink arsenic laced water, it doesn't mean it's good to do so.

We all love buying into these "it's xyz killing me!" stories but whats most likely causing you to feel terrible or potentially killing you is your lack of (quality) sleep, excess of stress, poor diet or potentially a combination of all three. And if I may throw my two cents in, humans were "designed" to live right around somewhere in the 60-70 range. This has been true since we kept track of humans, at least.
