You're exactly right. When you get to the point where you're considering weight-loss surgery, you've had multiple opportunities to look at the weight you've gained, realize you have to change and then do so. The people that get these surgeries never do that, they wait until they're pretty much unsalvageable to do anything (because realistically, the surgery can be bought and doesn't require effort). It's like looking at a tiny fire on the kitchen stove and not doing anything about it until the whole house goes up in flames.
