I would have hoped, Zoso, that you'd be spending the pre-surgery time practicing toe typing, or nose typing. Geeeeeez.
Seriously, I know it is a huge loss to not have your guitar and your golf...I'd be pretty upset about losing the summer too. But I guess the good side it that hopefully you will be able to relax a bit in the sun, listen to some excellent music and practice slowing down the pace a bit.
Prayers and good thoughts for a successful surgery and speedy recovery! (and no repeat of the past winter in 2016!)
