Given the impact running has on the joints, it would be great to do a program like this with a bike instead.
(Other than Peloton which obviously has a high entry cost and even their app-only experience is pretty expensive for what it is)
I’ve certainly noticed in the past big differences in advice. The NHS will downplay and not suggest investigations whereas another (non UK) site does the opposite.
The NHS advice surely is carefully crafted not to cause unnecessary (from their point of view) GP visits, tests etc.
The NHS follows a strict set of guidelines for the identification and treatment of illnesses. They do not act like medical businesses such as hospitals whose goal is to do as much testing as they can justify to get more money from insurers.
Wages will need to go up, which means the costs of goods and services will need to go up, and the city will get even less affordable.
Process design, interface design, organisation and manning, ergonomics etc all play a role.
It is inevitable that a human will make an error, with a well designed system it should be very very hard for them to do so.
