I am a mechanical engineer, born in 1953, PhD, Stanford, 1980. I have been actively working in the field of mechanical CAE for decades. I also have a lifelong interest in outdoor activities and fitness. I had both hips replaced and a heart valve replaced due to a genetic condition. This blog chronicles my adventures in staying active despite these bumps in the road. View all posts by BionicOldGuy
