I was installing pistons in a v-6 Yamaha block today and thought men give life to the world too. Every time we install pistons in a block we bring life and joy to the world. I looked down under my bench where there is a large box of bad pistons. Every engine I have brought back to life. It has made someone very happy. Women give birth we bring life to the world too. Every time we bring an engine to life. I always cant wait till they come to life. You sit there and listen to the first rotations its a great feeling.
