What does your son or daughter do for a living

Mike, I have to brag some. My Son is an electrical engineer and battery genius. He works in the medical field and develops cordless surgical tools. He holds several patents at 37 years old. My Daughter-in-law teaches graduate engineering students at Western Michigan University and is the one that developed the method of direct injection for gas engines while working on her PHD at U of M. Unlike me their both brilliant and have given Gramma and me 2 beautiful grandchildren to love. Dan
