It’s quite convenient to have a garden in the countryside. More local people grow their own vegetables. We have lots of bananas and bamboo for food.
I wish I could go hiking in Scotland one day, though I curd do short distance as I did injured my knees in water sport years ago. The mountains in Scotland look very dramatic and wild in the north.
just start with short hikes with lots of resting spots just in case. be safe when you do start hiking
