Arvin will unexpectedly ask some questions that I can't answer sometimes and need to think about it. I sometimes have to ask somebody and have to get back to him for the answer. Recently, he asked me why people response,
'bless you' if someone sneezes. Then I came to realized and asked myself the same question.
Have to asked hubby about this. And his reply was, in the earlier times,
plague was a deadly infectious desease, a lot of people died from this. And one of the symptoms of this pandemic infection is
sneezing, and people would say this in hope that the person who sneezed would not actually develop the disease.

True or not true? I googled it too and found this theory as one of the origin of 'bless you' response, but there are still a lot of explaination on why people say 'bless you' after you sneezed
