Small hairline cracks in bricks

We’ve got a couple of hairline cracks running through the mortar and a few bricks. Is that something to keep an eye on or totally normal on older houses?

"A picture would help considerably?
Probably settlement and likely historic but always keep an eye on the situation and check there is not any current movement.
If the mortar has shrunk it may need raked out and replaced to prevent frost action blowing the face of the bricks off."

"Good afternoon,
Although its perfectly normal to get cracks in older house due to the building methods, especially above windows & chimney breasts as these are weak points.
It may be worth getting a contractor or structural engineer to take a look & compile a report for you."

"Depending on how big and how far the cracks are and go but generally quite normal to find on old properties.
Very easy repair with heliflex rods and new mortor
