I left down there at close to 80, arrived up here at 17 I think it was. 11 the next morning when I shoveled snow, windchill was -15. Hands go numb in just a short while with no gloves on. You forget how miserable it is when you're out of it for a month or so.
I feel ya. Had a shoulder injury a couple years ago. Resisted surgery. Once fixed I realized I only extended the process. Long rehab but, all good now.
