He says he didn't go to the military because of his arm, but he plays golf?

Looking at the President's military exemption facts...
Around the age of sixteen, as his height grew by 15cm and the bones in his wrists and arms were developing, an accident occurred where the broken bone could not keep up with the growth rate of the other bones, causing the arm to twist and the growth plates in the crushed joint areas to break. Lee Jae-myung was given a Grade 6 rating, which is an exemption from military service, due to this condition.
This is what it says....
If he's in a condition where he can't serve in the military, how the hell does he play golf?????
I'm suddenly getting goosebumps?????
How is that trash playing golf???
I've played golf a few times myself,
did he play golf with one hand???
I'm just genuinely curious??
