Glad to hear you feeling better and congrats on the weight loss! Very nice floor, too. I have my work area in the garage covered with the black mats and I wear Crocks when I build so nothing hurts after an all-day build. My eyes are giving out..glaucoma, so I have to get a little close to the work and have the occasional neck ache but my sweet bride is a massage therapist so I do have is "made in the shade...or garage" so to speak. I have fits trying to find a #4 washer on that black floor though.
Well done,
Steve
