Do you really need a step counter?

Since when did we start to care so much about our health and start to do step counting? It was only popular with professional and hardcore runners and that type of watch is not cheap (now still expensive).

Oh well, due to consumer technology advancement, it seems like everyone does have a smart tracker device with them. So, today, I want to try out something new and not so popular yet brand, Coros Pace 2. I do love this watch and please continue to watch if you want to know the reasons.
