Were you a rugby player?
Up to 45 years ago I used to do many sports (kind of all rounder). After that, only judo, condition, jujutsu and that's it. And at 67 I see no reason to stop,
No running, cycling, weights, tennis etc.
Only at school, deep into last century...
The thing with the springboks is that it smacks of dabbling with performance drugs just as the sport was becoming professional.
Wind the clock forward a couple of decades and that (maybe) those dabblings are exacting a serious price
Other teams of that era don’t seem to have such casualty lists...
