When I was young, as I had absolutely no experience with many things, someone asked me on forums what the greatest thing you can take before physical activity is. I only typed one word, and explained it in my next post. Coffee. The explanation was that if your heart rate is already faster from one large coffee... it works in a smooth rhythm of consistency, and when someone hikes or walks fast or lift something, their heart rate maintains a balanced evenness. That the brain doesn't need to send signals for the heart to work faster or slower. Your coffee did it for you. It also gives you a relaxing feeling from combining being awake with physical activity which wakes you more, and the ability to think well from coffee, since it gives everyone that.

As I grew older, and I'm 33 right now, I've had second thoughts. It would be strong mints or valerian pre-workout, to relax you as much as possible before physical activity, so that it doesn't increase your heart rate as much, plus from relaxation from the single valerian, mint over the counter bonbon, or combining both. You don't feel a high later from hiking up the mountain paths, the way you would with coffee, but it's healthier for you and increases lifespan so that everyone who does this lives to a much older age than with having some coffee during your youth. I don't know if my thought process during my youth or this thought process is greater, I have no idea. When someone is newer they don't know how to think, because they aren't used to things [in the world for example] they need more time to catch up to someone older. However whether a young or older person makes something new, a concept, everyone is thinking about it, and as it's new for them they can make greater things from it.
