Good job. It can be helpful to think of five pound bags of sugar when considering weight loss. You've lost four bags of sugar - that was quite a lot to be carrying around. I still have a bag of winter weight to get rid of this Spring.
I'm 67 too and at one time hit 210. About 190 now and planning to get back down to 185 or less this cycling season. (Midwest winter screws with my cycling.)
Wondering how you went forward in time to 'December 2017' ?
