Single living men tend to have plainer houses and décor, fewer ornaments and less flowers, with a couple of items that reflect an interest. Just looking around, my few ornaments all have a use, my first fly fishing reel, vintage camera, vintage compass and a few shooting trophies that come and go. White walls and ceiling, Oak floor and leather and oak furniture. As Le Corbusier said "The house is a machine for living in".

There are always exceptions, but as a species, you can't escape mother nature.
