I sometimes wonder if VR is ever successful, perhaps in the 2050s, some of the idleness will be less of an issue.

The lack of movement rather than rich stimulation might remain the issuem I look forward to a study if there hasn't been one yet.

Muscles atrophy without consistent activity. VR can't replace that for someone with a broken hip / leg / spine. The whole cardiopulmonary system weakens with age, as does the immune system and healing takes longer, so an injury from a fall is much harder on the body than an equivalent injury to a younger person.

The comparison is between active VR participation (not simply watching TV in VR) and passive activities like crosswords during the recovery period of reduced mobility.
