I don't have an i phone or android or internet enabled phone. I just have an old Nokia 100 that I have had for years. Anyway I don't need an app to enable me to walk briskly as I have a little dog that likes to do just that every day
Now he is older if he doesn't fancy it one day I just go by myself.
The trouble is, every time 'they' tell us we should be doing this or that it locks into my issues with my upbringing and the worry that if I don't do it, or dont do it right then I will get into trouble, so for my mental health I am best not subscribing to the things 'they' tell us to do. They usually change their mind after a while and tell us to do something else instead
.
'they' must think we are all daft, it's common sense to try to keep well and active, we don't need faceless entities telling us what to do. For me, and this is just me, subscribing to something like this would do more harm than good but I hope everyone who is doing it enjoys the challenge and feels better for it
