I sure hate to stay very long, but we also live 50 miles from the hospital we use and I insist that our docs don't let us out too early "just in case"--my DH had appendix out and was little too late--ended up with bleeding ulcer that required 5 units of blood transfusion--and they had planned to let him out that next day--instead spent 6 days in critical care instead of an overnite visit. He had knee replaced a year ago--I've had both replaced and our doc keeps us in the hospital at least 2 nights as he doesn't want us having problems and being unable to get too hospital in time.
