I just turned 68 and have been doing 500 repetitions per day juggling 3# balls for the last five years. I haven't had any joint problems. To me it's just good exercise.
It depends. If you reduce your total amount of daily calories to your actual requirements and you still have an active life (not staying all day in home), you won't get fat. There is a lot of people who don't practice any sport and are not fat at all.
