Yes, a lot of people foolishly give out their age. But that's bad. Why? I'll explain the extreme scenario.

You reveal your age and birthday over the course of two years. I remember that. So I figure out when you were born exactly (mm,dd,yy). Then I find out where you live (your country), which you give out because you don't see the harm of it. That narrows it down, because only a few were born on your date of birth and live in your country. Then if you have different timezones for your country, I ask which timezone you live in, and you tell me. That narrows it down even more.

Now what if I had the resources to gain the information of every child that was born in your country on your birthday in your timezone on the year you were born? Then I'd get first and last names, addresses, family names. Maybe even credit card and social security numbers (depending on if you live in America or not for the social security). With all this information, I could a) Steal a ton of money from you and/or b) Track you down and kill/kidnap you/family+you/family.

^ Its extreme yes, and it may seem unlikely to happen to you, but it WILL happen to someone on the internet. And that someone is going to be someone who just spills out all their information. So in conclusion, this is just a really really really bad idea... I'm glad you're suggesting things though! Good for you! But its not a good idea (Safety first).
