should be no retirement age limit!
ok...i know it's impossible.
regarding the marital age, there's no problem on what age you are as long as you are over age and can AFFORD to have a family including able to support kids, if you are 30 years old,married but yet still earning pennies, my advice is dont even think to have more than 2 children. you not only suffer yourself but not having enough money to support their education and everyday life's need will affect your kids growth too.
let's say your kids are talented in music, but you dont have the money to buy them expensive instrument to encourage them(piano and other instruments cost a fortune).
ok,so you say let the kids earn themself what they want, but that would have kill their study time, activities time, social time, family time etc etc.
so the best advice should be work hard,safe hard while you'r still single, and married and get kids fast.
sorry for off topic...
i suggest that retirement age should be increase, at least to 60. see TDM, nearly 80 still active.
