Think it depends on how slowly someone wanted to drag it all out. I suppose if you branched out of Manhattan it’s possible, but even then, there’s plenty of time to twiddle thumbs.
Think it’s the job tbh. Climbing up and jumping down. The ear is for the job too, that’s not really serious though. They don’t ache a lot, just seize up when I’m sat down for too long. Standing up at the footy is a huge favour.
