When you're young and healthy, it's hard to consider a time when you won't be either of those things. I used to take my health for granted; I had a diet that consisted of a lot of fast food, takeouts, and other processed crap. I barely exercised.
I knew I needed to get my act together if I wanted to avoid the health issues that run in my family, but I always thought there'd be time to do that later. Thankfully, entering my thirties was that time and not only have I shed 120 pounds, but I've also completely overhauled my lifestyle to maximize my health and wellness.
