League Of Legends help save lives!

I thought of this idea earlier today. Millions of people are dying of heart disease from obesity and things of the sort. I actually am obese for my age. I am 18 years old 5' 2" and 175 pounds. I recently started working out. Running, lifting weights, etc. I wasn't really motivated until I started thinking about how it would be fun or cool to track my progress with a type of ladder/division thing. So I came up with a system I wrote down. Bronze 5 all the way up to Gold 1 would be weight loss. Platinum 5 up to challenger would be muscle gain.

I was hoping maybe riot would consider the idea of making something with the idea of tracking progress of getting in good shape with in game rewards. Or even just a line graph with the tiers and divisions listed so you can track progress and feel rewarded in some way. I think it would motivate a lot of people to get off there chair and get some exercise. Trust me I was in no way wanting to get fit 2 months ago. But now I found an awesome reason to. It motivated me and showed me what I am capable of. I was hoping sharing my ideas with riot or even you guys could help motivate some people. I think I have a pretty decent idea. Obviously it could be worked around and made fair and stuff so people can't cheat the system if it were in game rewards. But it could be things as simple as icons or skins that show "Hey I lost 50 pounds" or "I gained 50 pounds of muscle" let me know what you guys think!
