I will provide a bit of anecdata. I went from not really fat, but kinda just mushy to my high school weight when I was ~30 and started working out and did a lot of running. The way I was treated be everyone was drastically different(better). I then had a severe foot fracture that required surgery and 12-18 month recovery. Running has proven difficult even 5 years later. I am regaining some pudge, and notice that royal treatment I used to get is not there anymore. I will also say that my mind is nowhere near as sharp. 2020 is the year I get back in shape, and will see if that makes a difference again...
