Just wondering if anyone had any philosophies that would explain their desires to do steroids , or to pursue fitness of any kind?

For my self I beleive that existance is only acheived to any degree by the way in which we can interact with the world. Physically, an obese person could not run stairs for 20 mins thus they are inhibited by their physical abilities and can not fully experience the world in a way that an athlete could. So, it is important for me to acheive, physically as well as mentally, a high degree of ability in order to interact with the world in which I live at the highest level possible...
