Don't be in a rush is my opinion. The problem with getting back to work is you will prioritize work at a time when you should really be prioritizing health. I'm 60 and for the first time in my life really I'm seeing how great a 20-30 minute nap is in the middle of the day. And I am walking much more. You don't do that kind of thing when you are working. I say 6 weeks minimum, but then again, this is my Out of Office message....
