Kerry,
You failed to mention one other "convenience" from the "good ole days". That is the little house behind the house. Until you have dropped your drawers on a frosty morning when the temperature is hovering around freezing, and exposed your rear end and other tender parts to the elements, you haven't lived. Believe me, tlhere was no loitering on the potty on those mornings.
Your schoolhouse comment brought back memories. I only walked one mile, not 2 (and actually, it was flat...no hills either way...and I wore shoes...to school and church anyway), and the school was a brick building with 4 classrooms, one for each grade 1 thru 4. We had to go outside and walk around to the back to enter a small lunch room where two classes at a time could sit at picnic style tables to eat. The meals were prepared right there, on cook stoves (no frozen food in the microwaves for us) and it always smelled terrific.
Of course, there was no Air Conditioning im the schools and the temps were high most of the year (this was in Florida). All 4 class rooms had 4 or 5 really large windows on two sides so air could flow through. Later, in Jr. High and Sr. High, in much larger brick buildings, you hoped to get a corner classroom so you could have that air flow. Students in the rooms with just one wall of windows had to suffice with fans that just stirred up the heat. Come to think of it, by the time I graduated high school in 1956, I never had a classroom or home with AC. My first AC was a window unit I bought for a house after I got married in '63.
