Alas poor Fitbit Charge 2 I consign you to the bin. Six months of no GPS, then trying to convince me my 2k run was 800 meters, a poor show - goodbye old friend. Welcome Garmin Vivoactive 3, my new buddy. Oh how I love your GPS, heart rate and cadence sensors :)
I started learning the Alexander Technique in 1972, over 45 years ago and I can say from personal experience, you never look back. It's forward and up and life changing, ...one always goes forward and up....
