> What you call lifestyle changes I call “need to make a decision”. Well I'd suggest not downplaying it that way. Going from a junk-food-and-soda diet to a healthy one is a huge shift in lifestyle. You don't just make a decision one day and that's that. You have to make that decision several times a day, every day, for the rest of your life. Not getting enough exercise? You don't just sign up for a gym membership and consider it done. No, that's just the first step. Now you need to show up at the gym several times a week, and put the work in over and over again. An alcoholic doesn't just decide to stop drinking one day, then poof they're cured. That decision is just the beginning. What follows is some mix of white knuckling in the beginning and an ever-present vigilance to maintain sobriety. It's not just "I don't drink anymore", but also "I need to come to terms with this issue or that relationship", and "I can't hang out at the bar every night anymore". It's a long-term project, not just a decision. Getting a vaccination is not like that at all. It really is a single decision, once made, and never thought about again.
