DD:- I use surfing as an analogy to our life, the ride is short, it is the use of energy, it is exhilirating, it took effort (mostly by your parents) to catch the wave (life). Like time, the ocean water is stationary (on average) as the wave energy moves through it and you move forward with the wave, slicing through the water. With skill, and will (and a long enough board, you can ride the wave (your life) all the way into the beach sand. You might on the way in even catch a second break when the wave goes over a sandbank at high tide. If your lucky, your life (ride) happenes at high tide. like right now.
Waves like light have dual nature, both wave energy and particles. They become hitting particles when they break, become a bore. thats when the injuies occur, getting hit by a wave.
