Inspiration comes from the oddest places... I was in the oven room just now, baking some samples for a test I've done, when I was suddenly hit by a strong wave of intense heat and vaporised solvent from the depths of the oven when I opened the door. I was a bit woozy for a few minutes, and I'm pretty sure I lost at least a year of my lifespan there...
What I found interesting though was the fact that not only me, but all of us who frequent the oven room, shut the door with our legs, and stuffed the knobs into place using our knees.
Are we that lazy? Why is bending to stuff the knobs with our hands so difficult? Seriously if there was a way to open the door with our legs, we would do it... morever, our hands are usually laden with samples which had been removed from the oven... Helpful, aren't they? Good old knees...
I tried concentrating on what else I used my knees for (to check if the brain still worked after the dose of heat and solvent) and came up with this list:
1. When your hands are full of things and you want to move from one place to another, you push the doors open with your knees.
2. To balance a heavy load: e.g. a box full of papers
3. To rest a baseball cap/safety helmet. Apparently the size of the cap/helmet fits the bent knee perfectly
4. For self defence
5. If someone's asleep, and you want to wake them up, but the place is too noisy, a prod on the knee does the trick - 'tis a true story (The question of how can a person sleep through the noise still baffles me till today)
6. Do you have anything to add?
