‘Fiddly!’

Had to replace the battery in the chest heart rate monitor -  that I use when running - today.

Not difficult in itself, except for the the tiny screws! 

They’re minute - just a few millimetres long - and you need a special Phillips #0 screwdriver.

The really fiddly bit was picking them up in my ageing fingers and getting them into their holes, and sufficiently straight, to be able to start screwing them in!
