Sorry about making u feel old. Personally, i'd rather hang around the older crowd in the car/engine/high performance stuff. You can learn a whole lot and allow u to not royaly screw yourself by doing something stupid. My dad has taught me a ton of incredibly useful and vital information. If you must know, is 67. Currently, our 2 496 super chargered marine engines are completed(bottom end..these things r perdy). With them alone, i have learned a vast amount of knowledge about engines.
Btw, whoever said 18 is old, musta been high. I am only a year away, and i still feel so young....:-/. Not ready for the real world..haha.
