I had watches for years and as part of that I used to regularly take them off throughout the day and set them on the table where ever I was or such, because I never found them comfortable or for me they interfered with things (for me, probably doesn't help that I'm left handed for writing). Before I received my smart watch a year or so ago, I had fallen into a routine of not even wearing a watch anymore at all, ever for about a five to ten year period, any watches that I had were basically just battery dead in a drawer. When I got my current smart watch it was a massive nuance for me, wearing it all the time and to bed. However, I got over it. Sure it still interferes with things sometimes (and I basically never button up my shirt cuffs anymore), but if I (someone who basically detested wearing a normal watch) can wear a smart watch almost 24/7 now, then probably anyone can.
All the health and sleep and step and walk counting and reporting stuff, etc... that my smart watch can perform, for me that was fun to pay attention to and play around with as a novelty, for about a week. I barely ever look at that stuff anyone and certainly avoid tying into as many of the "health services/offerings" as possible. For me, I found most of that stuff to just be more marketing stuff/attempts than anything else.
