If someone is speaking proudly of how bad they are at math they most likely didn’t have dyscalculia. Most of us that do have it speak angrily or resignedly about how bad we are at math. What really gets me is when people proudly blame their “dyslexia” for why they are bad at math.
Might want to look into dirt bike protective gear. I am personally a fan of Leatt but there are loads of brands to choose from. I have never ridden a horse wearing dirt bike gear but I have hit the ground and trees many, many, times while dirt biking and it has served me well.
