I only have 1 watch. I wear it everyday - to TELL TIME.
I've had the same watch for the past 10 years. I'll get rid of mine for an Apple Watch.
I have 1 bicycle and 1 pair of shoes, so I don't understand why you think all people have many of those. 1 is plenty. When the 1 wears out, I get another.
Um... one pair of shoes for ten years? Do you work for a living, do yard work, play a sport, etc?
