So it is not amnesia, it is just a failure to influence their present action. This reminds me of my college friend who spent much of his spare time climbing the outsides of campus buildings, smokestacks, et al.. Then one day he claimed to be afraid of heights, which made me laugh. "How can you be afraid of heights when you're constantly taking risks at high altitude?", I asked. His response was something like: "Oh, I'm afraid. But I can ignore that and keep going."
