Human Horsepower

I’m sure you’ve seen the ads for those little energy shots you can get in all the drug stores and gas stations. They promise you that you won’t get that “afternoon feeling” and that you’ll get the energy of coffee without the crash …
…except it’s not true.
Those products stimulate you with synthetic caffeine. That makes them worse than, not better than coffee. You are going to get jitters and you’re going to hit rock bottom.
The reason that happens is that caffeine causes you to release an “energy transmitter” in your brain. The problem is that the caffeine causes depletion of this “energy transmitter.” Then, you feel worse than you did to start with.
