We lived in a city till we were early forties then moved first to somewhere slightly rural then in 2011 at the age of 44 to a rural hamlet as DH had always wanted to live in the countryside.
Didn't do it for me, although it had its good points.
For me the issues were (in no particular order) -
Badgers and moles ruining the very large lawn - one night I nearly shit myself when a badger shot from one side of the garden to the other whilst I was out admiring the stars!
Blooming enormous house spiders - everywhere, but usually on the ceiling over my side of the bed.
Knowing you could run out of oil at any time - got a Guardman guage to sort this.
The most nosey neighbours ever - knew everyone's business and made up all sorts of crap about people, including us no doubt!
No footpaths - so taking your life in your hands from speeding drivers when dog walking.
Bloody HGV drivers driving through unsuitable roads, wrecking the surface and Fix My Street not having the desired effect - think flaming Wilts council at fault there though!
Broadband and mobile fairly crap - not so good when running a business from home as we do.
Now living in a village right on the edge of a city and so far we've encountered non of the above.....
Horses for courses though!
