I noticed a title on YouTube, "How To Survive A Self Defense Attack".

Don't tell me, this must be one of those occasions in which the person who needs the advice is looking out for when, say, he will pass someone on the street who considers him an assailant of whatever stripe.

That reminds me of the cold war staple of the flat topped, formica-frame glasses comedians from whom Carlin and Bruce recoiled: anti-missile, anti-anti-missile-missile . . .
