As I read through the threads and the discussions around getting older etc. it brought to mind my husband's elderly uncle (no longer with us) who used to ride his bike to our place to visit his 94 year old sister. At the time he was in his late 80's. Uncle Lewis rode his old fixed wheel bicycle with confidence, but the mount and dismount was a little precarious as he struggled to raise his leg over the rear mudguard. Once he was mobile he was fantastic. Walking any distance was difficult for him but riding was a breeze.
