I drink occasionally. One small drink, socially, never more. I usually don't even finish it.
I've always known alcohol hurts. But it's also one of the most heavily marketed vices on the planet. Every ad sells the same story: fun, friends, freedom. Nobody advertises the bill.
Gen Z saw through it before the rest of us. They barely drink. Most health-focused generation I've seen… they looked at the deal and passed.
So I got curious about the actual mechanism. What does it do, and why does the damage look the way it does? Because one thing I've noticed just from watching people over the years: alcohol ages people fast. You can see it in the face first… the skin, the eyes, a puffiness that doesn't go away. I wanted to know why.
Here's what I found, plainly. The body doesn't treat alcohol like food. It treats it like a poison that happens to carry calories. The liver drops everything else to clear it first, so while it's busy, fat burning pauses. Seven calories a gram, zero nutrition.
The liver breaks it down in two passes. The stuff in the middle, acetaldehyde, is the nasty one… it's classified as carcinogenic to humans.
Then the brain. Alcohol makes you feel relaxed, but it breaks sleep apart. Less dreaming, and the second half of the night in pieces. You can watch it on any sleep tracker… deep early, shattered late. Knocked out is not slept.
This doesn't change what I do. One small drink, usually unfinished. But now I can see the bill clearly, and I understand what I've been seeing in people's faces all these years.
What I still don't know: how much of the aging is the alcohol itself, and how much is the bad sleep and late-night food that travel with it. That's my next question.
