SS, as other have pointed out stress for anyone is a terrible health hazard. It seems from all the stories we read the stress that is put on the LBS as their entire life is blown up, both emotionally, financially and in every day life is incredibly high. And sadly as others pointed out it seems to impact them very negatively in health (as we see over and over). MLCers are under a lot of stress, but they also seem to disassociate a lot, so they may not be aware of it. It probably does impact their health negatively, but so do their life choices (again see all the stories of sudden "aging" and general demeanor). Difference is the LBS didn't make the choices that led to their stress.
I wanted to post an amusing "update." A couple of days ago I had a conversation with my "wife" where she wanted to know whether her OM could attend a private event I am hosting for fun with a group of friends. I indirectly waived the request off as the event has already been arranged and there is no more room. A couple of hours later I got a text asking whether I had an issue hanging out with the "OM" and whether I wanted to go to a trip with her and OM. I simply responded that it wasn't an option as the OM is not a friend and is not someone I know and hang out with.
Yup this is just another example of the non-reality of the MLCers "reality."
