When I first began to suffer the infirmities of growing older, I did gravitate towards larger scale. However, a problem soon appeared- display space.
Further, I began to ponder the old saying, use it or lose it. That is, if I stop stressing my eyes and fingers, does that become a feedback mechanism that lowers my abilities. I decided I needed to work harder on the abilities I was losing.
The consideration of both of those problems has caused me to return to smaller scale- 1:700 ships and 1:72 and :144 planes.
