In light of the severity and invasiveness of cardiac bypass surgery, I'm going out on a limb and saying that's very hard to believe.
What @Moppys_jalopy said rings true to fact:
Geez y'all must not be self employed. No work no pay. Operation on Friday pm, went home Tue am when my wife came to visit. They were kind enough to give me 2 johnnies to wear because it was mid winter (Ides of March) and my wife didn't bring any clothes as I was not expected to go home until Wednesday. I passed the stair climb test and was heading up to the next floor when the nurse called me down. I went to a stockholders annual meeting that evening as I was on the board of directors. I had hired a guy to work my shop but only needed him one day. I don't know what a VCR weighs but I had plenty of them to fix. They told me to pick up nothing that was over 10 pounds so that's what I decided they weigh. We had a wicked snow storm around April 1st and I was out there putting the plow on my Jeep 2 weeks post-op. By mid April I was out doing house calls again. The first one was a big one I had ordered the module for the day before the heart did it's thing. I pushed it away from the wall with my legs so I didn't pick it up. If it felt like I was straining something (usually in my movable collar bone, I stopped to rest or found a different way. When I started rehab they had me doing 100 pounds on the pick em up machines while most of the other guys who were all friends of mine from school and life were doing 30 to 35. I used to run up the stairs to the 4th floor rehab because waiting for the elevator was maddening. Two stairs at a time because the spacing of the steps was tiring if you did one step at a time. After the collar bone chose a spot it liked things were better. It didn't hurt but hearing and feeling it click was disheartening.
BTW I loved the rowing machine it made me feel great and seemed to work nearly every muscle. Arms, legs, back,stomach, oh I wish I could afford to buy one for home.
I used to bring a rechargeable soldering iron because they had a couple machines that had external wires that kept breaking so I was their fixit guy.
Occasionally I meet one of the drill sergeants from rehab. Last time was about 2 months age at a free skin check the hospital did. She was one of toughest ones, also the sexiest.
Took me years to find anything about the bypass operation on the internet unless you were a doctor and able to sign in. After I finally did find sites that let us peons talk I found that a lot of people had really bad experiences with it. Of course right after the op I felt like I had battled a Mack truck and lost but after coming home 4 days later the worst irritation was those dam staples in my arm and the "deflected sternum" they left me with. That's what they called it at the VA but I think it's the xiphoid process. At the hospital they said it was a hernia and offered to fix it for an additional $20 Gs. I said I'll just remember to NOT hit it on the steering wheel cause that hurts like hell and leaning over the fender to work on my car didn't feel so good either.
If you had a bad experience I'm truly sorry for you but mine wasn't bad at all. In the hospital the beds were hurting my back the most and I was glad to escape.
