Yo, Brother..been thru exactly that kind of circumstance...go in thinking it's one thing, come out a day later with five bypasses. Don't worry....we are not in control, really...the body does what it does, and we're just along for the ride. Eight years later, the number 5 bypass (lowest down on the back of the heart) failed...I'm a little short of breath, but I'm still teaching every day. God bless you, and yours.
