Being on SSDI, I kind of resent being lumped in as those who need it don't get it and those who don't do. I am not ever sure if I can get out of bed in the morning and if I do what my pain level is going to be. I have multiple illnesses as do many of us and they all feed each other. I would gladly give us SSDI for good health, trust me.
If you really know cheaters, there must be some way to report them.
I have found that the older you get and the longer you are on SSDI the less they hassle you. I think the feeling is that you are only going to get more ill and older. I finally realized that even if a cure were found tomorrow, I would never be 28 again.
