Hi,
I too have been retired for 1 year, enjoy.
At home, the fireplace is a bit on the side, it is in white Provence stone (because I live in France) and African green granite, there are 2.5 tons of stones.
The fireplace is good to calm down and watch the fire during winter evenings, it is good for your health to dream in front of the fire, found AK6s and you will no longer need (too much) corners.
