If I were to be living in the year of 1899 I would chose not to smile.The reason for that would be because it was put as a label of being mad,crazy or just having a bad trait.Along with that reason scientists also believe their were other reasons as dental hygiene,and the old photos were taking a long time to be processed,meaning holding a smile for a long period of time would be difficult.

They didn't smile in pictures in the old days because they had very bad hygiene, so they would look like a shark with very yellow teeth, with bad breath; It was rare for them to smile, cause they would get bored often waiting for the picture to happen, which took like 12 minutes.

They had bad teeth and the pictures took forever to take. Pictures were also influenced by portraits were they don't smile. No I don't like taking pictures. Because you have to stand still forever. I would just have a regular photo of me. No I won't smile. I would wear regular cloths.

People probably didn't smile because they must have of had bad teeth or maybe because they weren't used to smiling when they take pictures like today! :)

# data[].attributes.body
They didn't smile because either they didn't want to smile or because they thought they were ugly at some point of their lives. Also they didn't want to smile or they just didn't like to take pictures or never wanted to smile in front of pictures. Also, they just like to smile when there was no cam in front of their faces.....:))))))))))):)))
