Well as a fun exercise.,let me see how many personal facts I know about you
1. You are from California. This was supposed to be easy, as I believe you have put your location on profile, but I have not looked it up.
2. Your name is John
3. You are the person who evangelizes water cleaning of pipes
4. You are married
5. You have tried to grow a beard / mustache multiple times in your life, but they did not agree with you so you are clean shaven
6. You watch a lot of sports on TV
7. You use golf tees as tampers, so I believe you play a lot of golf
8. You smoke in your car when your wife is present
9. You drive German cars, and I am inclined to guess these are Mercedes. In fact, last 7-9 of your cars were German
10. Your hobby is photography but after a wedding shoot, you decided that you will not shoot wedding any more
I got 10 facts about you just by remembering your posts
Yes, there are many times when location is totally irrelevant. But when it does matter—maybe 15-20% of the time—it's such a small thing to take two minutes to appease those who care.
