One other thing, which I thought was hilarious. When I looked into why Google was giving me such weird search results, years ago, I found out that their bots had decided that I was a 65-year-old man (which I am not by the way!). I think this was because I sometimes look up 1940s jazz videos on YouTube.
I decided not to enlighten them. I even started to get YouTube ads for incontinence pads for men! It's only recently that I started to get ads targeted at women.
