It is not common to wear watches for more than a few days at a time simply because there are not many whose battery will last that long. The effects of fatigue/pressure point from the sensor bump are less observed but not missing. With 30 days on wrist, I can extrapolate that fatigue will be more pronounced - so I am calling it out. I understand I am a small sample size but I have 2 watches whose battery lasts 7 days and the one without the bump is more pleasant to wear for a week between charges. To the point that I always reach for the comfort option and eventually sold off the other.
On a lighter note, I do hope I'm not providing a series of increasingly bizarre and nonsensical questions or scenarios ;) https://www.youtube.com/watch?v=8YDpvMYk5jA
2. People already exercise in metal straps and aluminum Garmins.
These just seem like you-things. Which is fine, but you should temper your complaints/bikeshedding accordingly.
