I definitely practice 1 and 2, seem common sense to me, but for the others, not so much. 
Oh also, avoiding tripping on steps, adopt the high straight legged walk of a storm trooper or of John Cleese at the Ministry of Silly walks. I really must dig out the Horst Wessel song and play it on my progress from bed to kitchen. 
Apparently no denial. Seems like a good halfway house berween UK and US-type systems as this seems to mean care for pre-existing conditions is “socialised” into CPAM+mutelle arrangements here.
Pretty sure that for standalone policies that are not mutuelles held by someone covered in CPAM, then probably pre-existing is not covered, same as with other standalone policies.
I think Fabien mentioned he offers a policy while someone is getting things sorted out that could convert to a mutuelle as and when the holder has been accepted by CPAM.
