It’s a fair question. There are a few reasons to shop now. One is that I still have my independence. One big reason for the long recovery and a threshold for returning to work is when I am permitted (not able) drive. The danger of sternum infection x the likelihood of a car crash with airbag means they keep a long prohibition on being in the front of a car. But our vehicles have kid seats 3-abreast. Modern cars no longer have a shutoff for the passenger air bag. So I’m going nowhere most of the time for 2 mo and only at the pleasure of my driver and availability of a babysitter. After that it’s mainly about risk of a serious fall, that’s why a trike. Another reason is that I really wanted to try it while I’m still able and not approaching it as a neophyte while already handicapped, to see if it’s something to enjoy. And finally it’s fun to be enthusiastic about something in the face of a depressing problem.
