 Person2:  Bob is retiring , wow ... that's news to me , I had no idea Bob was that old , retirement's still sixty-five , right ?  
 Person1:      Retirement age is still 65 , but I think more and more people are retiring earlier , I think Bob's in upper fifties already , he just looks pretty young .  
 Person2:  Wow ... I thought he was early forty stops , why would he want to retire so soon ?  
 Person1:      Well , I think you prepare it well and capture good savings , retiring early can give you a lot more time for travel and other activities , you should get out and enjoy the life you still can't , don't you think ?
