Very good point. It would be sad if the medical world stays too dogmatic, because a device that makes you wanna live is as important as a safe vehicle. At least I believe that's it's a win for everybody, that person may be far proactive mentally, physically[1] and socially; lessening the load on their close ones, and maybe other related bills like pain pills or other treatments.

[1] I buy the argument of being constantly trying to balance. These sets of muscle are rarely trained yet very very impact-ful on both body and mood.
