He passed from cancer several years ago. Don't feel bad you had no way of knowing. That was my "real" dad. The.one I call dad is in better health than me. Eats right, exercises, gets in his cardio etc. I've given him advice before on his protein intake and training, so has my youngest sister. Anyway, that's a twisted up mess of a long story. My "real" dad passed his bad genetics to me. Familiahyperlipidemia, vascular/heart issues and cancer. Oh joy. He didn't try to do anything about it. I refuse not to.
You might have me and the OP mixed up. Nonetheless, we do have a similar situation.
