You steroid pumping genetic freak...
Oh, wait a minute that's not you.
Most people just have crappy nutrition and don't work out consistently. They assume you are doing the same and therefore are getting your results from a needle.
Just take it as a compliment that people think you look like you are on steroids. At least you are getting their attention, some of them will even listen to what you have to say.
Activism is tough work, most of the time you don't have any idea who actually listened to you and started to change their lives. Then you will get surprises like your old friend you met at the gym this summer. You had changed his life and never even knew it. Stuff like that makes it all worthwhile!
