Adrenaline, as we all know, is a chemical that makes humans more alert and give us strength we never knew we had. If adrenaline could be accessed whenever we wanted, we would be unstoppable in sports. People have been known to jump over the fronts of two colliding semi trucks when major adrenaline kicks in. Action games would be too easy. But adrenaline only comes if you are in a tense situation. Rage also brings adrenaline. But the time when adrenaline really kicks in is life-threatening situations. If the brain can be fooled into thinking danger is near, than people would be unstoppable. Adrenaline would allow people to work longer, harder, and more efficient. The only problem is the toll it would take on the body. But that would help people that have sleeping problems get to sleep easier. So, ironically, bad sleepers would be the best workers. The problem remains of how to unleash the adrenaline without people about to be killed. The simplest way would to store adrenaline in a container and inject it. But this would result with only a few seconds of adrenaline rush. If we had something inside ourselves to release it as soon as you need it, like when a 10-year old kid wants to dunk, would be the best possible way. If pursued, this tech would be out in maybe 5 years. Look out world! Here comes the superhuman!
