english: Now, either we're all just becoming really grumpy as we get older, or it may mean that as you understand laughter better, and you are getting better at doing that, you need more than just hearing people laugh to want to laugh.
non_english: Nuž, buď sa všetci vekom  stávame mrzutejšími, alebo to môže znamenať,  že keď lepšie chápete smiech, a zlepšujete sa v tom, potrebujete viac ako počuť smiech iných, aby ste sa smiali.
