apart from the normal ones: balls/flying objects above the size and weight of a badminton ball.
Its because at every opportunity someone accidentally threw a ball into my face.
It got to panic attacks after a shoe landed in my face.

The fear got to the level i can only get to close proximity of a sport ball if i know the intent of balldirection is opposite of where im standing (its possible for others to kick a ball to a goal but not to kick it back, they would need to carry it). Else i dont even visit very ball sporty places
