Parhaps clarification is needed
I'd rather climb 5.12 with a hangover than 5.14 with an eating disorder.
Means he would prefer to do one or the other, and lightly implies that the two can't go together.
But then again, if you are anorexic, and climb 5.14, it also follows that you can climb 5.12. And, since it is apparently easy for an anorexic to get drunk (being hungry all the time, after all), we can then conclude that the two are NOT mutually exclusive. Further, since the 5.14 anorexic climber CAN get drunk, and is still classified as a 5.14 climber, we can conclude that he/she can get drunk and still climb 5.14
SO
Based on this statement,
I'd rather climb 5.12 with a hangover than 5.14 with an eating disorder.
It follows that:
1) You can climb 5.12 hung over
2) you can climb 5.12 with an eating disorder
3) If you are a 5.14 climber with an eating disorder, you can still climb 5.14, but, more importantly,
4) you can get drunk as hell and still climb 5.14
