If there's ever one thing that someone could do to stop aging, it's lift weights—and don't stop. And don't do it for vanity; do it because you want to keep your tissue. Think of it as, like, age is like a little demon that's slowly robbing you of your tissue—your ability to walk upstairs, your ability to open up jars, your ability to open a car door when it's frozen. All that shit is real, and the only way to stave that off is weightlifting.
