You're saying, but I have to go to the gym to work out my stress. Dude, maybe you should learn how to work out your stress without using opiates from exercise because your body won't be able to do that when you're 70. Actually, it might be able to do that when you're 70 with all the anti aging, but why are you wasting all the time? So if you have stress, deal with the stress instead of medicating it with over training in a way that doesn't cause your body to transform and take the time and the energy that you save and use it to meditate, use it to serve others, use it to be nice, used to be kind. Use it to pull your car over and help the old lady across the street to save a puppy. Do anything other than sit there in the spin class with someone going, you need to pedal harder. Like fuck that.
