What's a body life hack you can purchase?
A couple years ago I changed my life by getting LASIK and I still can't believe money could buy this much impact. Do you have any other similar "life altering" things you can do to your body for money? I suppose this includes food and drugs..
1. Exercise it to be fit and strong.
2. Eat good food.
3. Get good sleep.
Most people don't do any of the above 3, let alone all of them. Start there.
Adopt the Mediterranean diet, people who do tend to live long, healthy lives.
