I guess that depends what you determine a success.
In my mind any life saved or made more comfortable as a result of this makes it a success.
The biggest question is will it pull in people who dont already look at the health of their body?
I think it’s a it like 50 shades of grey. How many women would have gone to the cinema to watch a pron film? I guess not many but turn it into a socially acceptable normal thing with advertising and people are suddenly less ashamed about going.
The embarrassing bodies tv show used to get random people in who wouldnt normally have gone to their gp because they could see someone they wouldnt have to see again so I think this stands a good chance of helping a number of people.
