The GPS analogy in here is exactly right. I still know how to drive, but I genuinely cannot navigate my own city without it anymore. I didn't notice it happening.
The neat bit is that it doesn't necessarily need to sample 82 Hz directly. If the sample rate is known and the target is one of a few guitar strings, the aliased peak can still be useful. The tricky part is probably rejecting the wrong alias once the vibration signal gets messy.
