Daddy is home and doing much better, although I find it disconcerting that there is still no diagnosis for the mysterious autoimmune disease they say he has. It was pretty touch and go there for a couple days, but he's home and even back on his exercise bike! I guess the good news is that they've ruled out any serious issues with his heart. However they discovered he has an enlarged heart and diabetes on top of the prostate cancer that he's been dealing with for a few years now. But my dad is a positive person, deeply religious, and proof that attitude is everything.
