This is soooooo true, its a real simple research. Have seen so many people after getting married they stop taking care of themselves like they used to do before. Secondly, yes after maternity obviously there are physical changes in body but after words you can always trim those back. Its upto you how you want to look like and your motivation to look as you used to be. Its tooooooo personal and varies person to person, generally speaking I agree with this theory ………..!!!
