Unpopular opinion: I thought lime mortar was just for old buildings until last month

Three years ago on a job in Savannah, I saw a guy repointing with it and thought it was a waste of time. Last month, I had to fix a wall on my own house that kept cracking with modern cement mix. A supplier in Atlanta told me to try a lime mortar for its flexibility, so I mixed a small batch. The wall hasn't moved a bit since, and the color match is perfect. What's the oldest building you've worked on that needed lime?

Heard lime lets old brick breathe, which is why it lasts.

Remember my buddy who used modern mortar on his 1900s chimney? That thing crumbled in two winters.
