Are wanderers' physical ailments a pre-incarnative choice?

[sjel]

Almost 100% yes, I would say. Either for their whole life or in certain special circumstances that call for it. When Franklin Roosevelt began to desire power more than was good for him as STO, he had programmed it into his life to become crippled if that situation were to arise:

I understand that in Roosevelt case that was a pre-incarnative choice, but I believe that choice is not limited to wanderers, anyone close to graduation can preemptively program in catalyst in form of physical ailment pre-incarnation. So in my view that in Roosevelt's case its more a pre-programmed catalyst in form of a physical ailment than the physical ailments "due to the extreme variance between the vibratory distortions of third density and those of the more dense densities" that's more unique to wanderers. 

For example, Carla's rheumatoid arthritis. It seems to be a physical ailment caused by the difference in "vibratory distortions". It seems that her pure and intense dedication to love/light/one infinite creator maybe related to the condition somehow. In that case is it best to live with it rather than heal it? Can it be generalized to say that all physical ailment due to difference in "vibratory distortions" need to be accepted rather than healed? I'm not looking for an answer, just your thoughts/views/inputs. _/|\_

I don't understand Carla's arthritis and major health problems if it is just due to vibratory difference. Cause Ra also said that those who are living the Law of One are noticeably more vibrant and physically healthier. Wouldn't her extreme devotion and joy have healed all the ailments caused by vibratory differences? The only reason I can think of for her lifelong physical troubles is preincarnative programming.
