How many days should you wear a shirt? It's autumn in Sydney, and it's getting colder. If you have a laptop-pushing job like mine, you can actually reach the end of the day without cracking a sweat. Actually, if you have a laptop-pushing job like mine, where you also sometimes work from home by yourself, you can sit there wearing your wife's t-shirt that you slept in with the words 'I'm with stupid' lovingly texta-ed on by one of your daughters, and no-one will be any the wiser (no, fifi has no such t-shirt, but you get the picture).
So is it OK to wear a shirt 2 days straight? What if you get to the end of day 2 and it's still fine, in your opinion? What if you take it off and lie it over a chair for a few days, thus allowing it to breathe, and then wear it again? What if you're only seeing people off in the distance most of the time, or out in the open air where the odour of stale sweat is not nearly as obvious?
All just academic questions, you understand. But the washing does mount up a bit in winter.
