<prompt> Human: Have a few questions regarding this:1. How did they calculate this? Is it solely based on the number of years worked and salary? She has only worked the minimum 10 years, a little above minimum wage. Does 210month sound right?2. I guess she could wait until she is 65 to get a little more, but will she get more if she stopped working and isnt planning on going back to work?3. My dad is also on his benefits right now, over 900month. So Im wondering whether she can go on his benefits instead of her own since I heard she might be able to get about 50 of his benefit amount, which is a little better than the measly 210.  <response>: Not to be a jerk, but early retirement is for people who can afford to retire early. Why hasnt your mother worked and is there a reason she cant work now?
