They hide it because that is personal information that no one should has access to unless you give them permission.
Thanks for your response. I agree with you. For security reasons
You’re welcome
My age does not really matter. What matters is my date of birth due to security reason same as my salary.
Your response is cool. It’s a personal information
People may hide their age and income for many reasons. It could be because they are ashamed, want to remain humble, or don’t want people judging them according to their age or financial status. Hiding your salary could be a good way to protect yourself.
You are very right. People hide those informations because of reasons known to them
I hide my age date of birth for security reasons you can’t trust the Internet these days lots of identity thieves. And I hate my salary because that is my own privacy!!
Your points are great. Thanks for your comment
You hide your age to avoid stigmatisation from certain individual. Hiding one’s salary is for security. You know sometimes you can even trust your spouse and some of your confidants.
Thanks for your response. I think you have a point

Thanks for your response. You are very right
