Mirrored Back Brush
Out of all the inventions on this list, this one might be the most pointless. Why? Just why? I can’t even. Imagine being so devoid of brain matter you can’t brush your own back with a normal back brush. They can’t do anything regarding their own body without a direct line of sight. Really? Then how do they even wipe themselves after using the bathroom?! Can’t scratch your own back? Well, good luck with this thing. It only requires perfectly aligning a pair of mirrors that jerk in all directions while you use it. The brush isn’t even angled properly. Just useless.
