birth order.
I am the oldest of three, and second to a missing fourth.
I am by far the most dynamical. I was v8 daily driver that went to drag strip...then top end daily driver goal of 165...then trouble, and calmed down years ago. My younger brother lost his license years ago, lives in a city, and is ecomodding beyond us all. when he was roadworhty, even had a motorcycle, thinking of fuel, and in maine that is not friendly.
My sister, she is like 2 feet 3 inches tall and insists on a 57 foot long extended yukon. There is a delusion.... I'll just call it american. do the opposite of yourself, "everyone" else does.
I settled for physics of answering "worlds greatest engine", but education gets ya thinking anyway...
