You will feel good. You will not be embarrassed at social gatherings. You can be a role model. And people will wanna be you. You will get big muscles like Brayden Giles. Your chance of heart failure and other diseases will greatly decrease.
You have greater chance to have heart failure when you are just sitting around. Only 1:3 people are physically fit. And only 3:7 people do regular exercise. You will watch people being strong and you will be jealous. Then you will have a sad life wanting to be someone else.
