Congratulations! I can certainly sympathize with wanting to get your weight down, for me I'd like to lose around 30 lbs. I should probably lose more, but the initial loss would be wonderful. I would love to do long distance walking & jogging like I did when I was younger, hiking too, but that stopped after several hundred pounds of lumber being dropped on me and hurting my knees. It's even more difficult to find motivation after what I was told was a particularly bad case of shingles hurt my back last year. All the doctor really said was "Ooh, this is interesting" after looking at it.
Either way, I should try my best and aim for more activity, and certainly get better about my eating habit. Ihope you and yyour wife continue to progress towards whatever goal you have set!
