mind sharing what you could have prevented?
Pushups are a good way to blow off steam when you are stressed out but, since you just had surgery, that's probably not gonna work. When I had surgery, the last thing the operative nurse said before I went out was "walk, you'll get better faster" or something like that and I tried it out, very tenatively at first, as my guts felt very unstable, but just around the block and I think it helped me recover pretty fast. The dog was really happy, being walked like 4x/ day. She's probably like "what the hell happened?" since then.
