Switching dominant hand forces a child to retrain their dominant hand and Lefties are Right brain dominant. Switching forced me to retrain against my wiring and in my humble opinion, it messed things up.
As I’ve grown older I find it interfering with my left/right brain working smoothly. So there are glitches as they say. As an artist I’m sure it affected my creativity.
As an engineer it helped.
Maddening!.
