What do you regret doing to your body?

Not taking care of my teeth :(

I have a MASSIVE tattoo on my left arm that just says “YOU” in huge block letters. I thought when I was 18 it’d be funny to have “a tattoo of you” on my arm. It’s too big and blocky and black to cover up and I just hate it.

Gaining a lot of weight really quickly. I've lost most of it now, but I have permanent stretch marks on my arms, thighs, stomach, and back. It fucking sucks.

Loud noise exposure. Now I have constant tinnitus.

Filtering what seems like about ten million gallons of booze through my liver and kidneys over the past ~15 years or so

I let myself get up to 602lbs....finally after not being able to walk longer than a block or being able to do simple functions I said enough is enough and joined myfitnesspal. 460 days later I have lost 252lbs and now weigh 349lbs.

I have a horrible habit of picking at my skin. Its nothing major, but I do have several tiny scars from it. They will likely be permanent, but I just can't stop! I do it without thinking. When I'm bored, or not doing anything else.

Many years of recklessly avoiding sunscreen. I'm only in my 30s but have already had on basal cell lesion removed. I hate to say it but I know there is more where that came from.
