Thanks, Very. That's amazing at the cost of your housing! I could live quite nicely there if the rents are so low. But that will be a few years down the line. I would prefer to live in the country (I'm an avid gardener), but right now we need to live in the city for a while.
No, I'm actually older - and I'm starting to have trouble driving here so it's probably best that I don't plan on doing it there, unless retirement sharpens my perceptions up a bit! My daughter will be at the Uni, so we need to be within walking distance/short bus trip of it for the next several years. Once she's done there, I fully expect she will need a car. Until then, I'm good with walking/buses/taxis/trains/paid tours and saving the expense of purchasing, licensing, maintaining, etc., a car that's not essential equipment. I've traveled a bit in the UK both with and without a car. (Mostly in late Winter and early Spring.) I actually rather enjoy getting off a bus or a train with a backpack and hiking a bit to somewhere with a nice pub and a decent room to spend some time in. How long I'll be able to do that - who knows? My bucket list contains walking Hadrian's wall, as far as it's walkable, someday (yes, that's England), and doing at least one of those epic Highland walks. Am bringing my walking stick (hiking stick, not a cane, not sure what it's called there) with me. All I'll need is a long gray robe and a beard and I'll double for Gandalf. 
There are lots of excellent walks not far from Glasgow. Loch Lomand is only a short trip away and has amazing scenery. There is also a train that runs up the west of Scotland and stops at lots of lovely little places such as Tyndrum - which is a start point for one of the most famous walks, the West Highland Way. There are lots of great places north of Fort William. I have just come back from Glenfinnan which is stunning and of course has the Harry Potter connection if you are a fan of that - the viaduct filmed in the movie is there and they run the same steam train along it from Fort William to Mallaig. From there you can also get a ferry to one of the remotest villages in the UK mainland and see whales and lots of other wildlife at the same time. It brings you back in time for the steam train return to FW.
Even around Glasgow itself, there are masses of parks with country walks - Glasgow is the greenest city in Europe.
One of the hidden gems of Scotland is Durness. I would highly recommend it.
Probably the best thing for walkers is that we have Right to Roam, which means there is no such thing as trespass, so the country is pretty much available to walk
