I shoot a lot of still life although I think the reasons are as much to do with practicalities as a love of the subject.
The challenge of creating a work of art out of a mundane subject is very appealing.
I also think convenience and being in control is a major attraction for me. I get jittery when trying to photograph outdoors when people are around and I have never learnt to drive a car so landscape photography is not so easy.
Reading John Blakemore 'Black and White darkroom workshop' has inspired me to work on still life projects rather than individual images.
