Yep - fork in mouth disease is the real problem. When you get weight off it hurts less to exercise - vicious circle, but you have to put in the work. I row as well - both on a machine and on the water. Best possible impact free exercise. I'll do a minimum of 5k pieces. On the water my route is closer to 10k. That's a workout.
I'm 6'4" and when my weight gets up around 190 I start to feel it in my knees. 180-5 is much more comfortable.
Another thing to look at as we age (I'm 59 in a few days) is your GI health. I had my gall bladder removed several years ago and my digestion is all different now. I take enzyme supplements to help with digestion.
Completely cut out junk foods - soda, oily chips, etc. Snack on fruit or nuts. Hold the vino to a glass a day with 2 or 3 days per week as "school nights" -no alcohol.
