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: Ya yaşlandıkça hepimiz daha somurtkan oluyoruz ya da kahkahayı anlamakta ustalaştıkça, sizi güldürmek için kahkahayı duymaktan daha fazlası gerekiyor.
