I swear this job I’m doing is making me look older quicker.

aging is caused by damage when dna replicates, causing weakened functions. stress, bad diet, not sleeping well, these all accelerate the aging process

Stress ages people dramatically. A fun game is to look at pictures of presidents at the beginning of their terms vs at the end. They all look considerably worse.

The science behind the link between chronic stress and aging is rather complicated but my basic understanding of it is that psychological stress causes something called oxidative stress which is a state of excess free radicals in the body. Free radicals are a specific type of molecule that can damage all types of cells in the body. When free radicals overwhelm the body’s ability to regulate them, I.e. when the body can’t produce enough antioxidants to combat them, the damage to various molecules in the body builds up and leads to many consequences, one of which is the acceleration of aging.
