I was onsite at a showroom which sells shoes with metatarsal protection. I remember asking out loud, "What is metatarsal protection?", and an employee described it for me. Since then, many of my targeted ads have been for protective footwear.
After some Duolingo learning, I began reading sitios de noticias en español, and noticed as many ads changed to Spanish.
It feels eerie knowing my phone is a rat, but it's pleasing to throw noise at advertisers.

A claim is as good as its veracity.
