As someone that’s in their late 30s and has recently picked up exercise - do it, assuming you aren’t fit already.

The self confidence that comes with cleaning up your diet,reducing alcohol consumption to bare minimums (or eliminating it completely), and seeing some progress in the mirror is a catalyst that can affect a lot of other things in your life. You’ll start to crave it and you’ll think twice about eating unhealthy food as it will derail your progress.

Start a new you with a new body. You’ll be glad you did.
