Humans started making tools about 90,000 years ago and it took all that time for us to realize we could put our luggage on wheels.

Whoever first came up with that idea is brilliant and we should all bow down in obeisance to that genius.

Here’s another simple but perfect invention that I first discovered this week: handbag holders that can stand beside your table. How awesome is this?

Also high on my list of pleasing finds this week is the talent that can make ordinary towels look like animals. My hat goes off to the housekeeping staff at this hotel who do things like this.
