I haven't had any problems with the pacemaker. I walk quite a bit in my work (land surveying). I have been surveying a hill farm and Thursday my Microsoft Band said I had walked 3.1 miles and climbed 57 flights of stairs. I think I can ride my bike OK.

Now my shoulder and arm are hurting and my hand goes to sleep. Doctor thinks it is a pinched nerve. Getting old is not for wimps.
