(NB: I only know about this phenomenon through my own experiences with failing-switches in my FAs.)

I ask this for a reason: I've been reading how difficult it is to do certain tasks (the obligatory flying, morphing objects etc.) and - when I LD hopefully some day soon - I'm hoping to kind of rationalise the impossible with the rules of science.

Example: It's not a flying chair, it's a chair with four jet-packs attached.

Example 2: I'm not really meeting the Beatles, it's just four good lookalikes with comprehensive knowledge of the Beatles.

etc.

But I'm thinking this: a lifetime's experience with lightswitches, and a little knowledge of science, has taught me that 99.9% of the time a light comes on when you flick a switch. When isn't the 99.9% lived out in a LD when it's absolutely what you expect to happen every time?

And does science regularly fail in LDs and my 'scientific explanations' won't achieve what I want when I LD?
