i'm glad this question was asked, because it sums up MJ's career. it's all about the magic. everything he does, sing, dance, 'fall' fall(maybe) 'fall' off of scaffolds fall off of scaffolds(maybe) smooth criminal lean 'falls',(if he falls) resting on the ground, being 'helped' up. and all the great moves, always look well choreographed, and are always up for endless debate, along with the singing. you know why the debate is always endless? because the main ingredient is the MAGIC.
and now he's ready to do it again. he has always done the most vigorous, taxing, yet beautiful, and exciting act ever to be done on stage, for many years. he's just had a vigorous doctor's exam, with a guy supervising, whose money is on the line. you would think, by now, after all these years, and all that stuff done on stage, MJ would walk with a limp or something. but, as seen, his walk is as magical as ever. and the doctors found no nicks or scars or any evidence that he did anything other than stand still on stage, or relax, all these years. that's how perfect the exam came out. all that is due to the magic, and the reality, that we all know, that we are overcome by the MAGIC. that, indeed, all the performances are always perfect. his current condition is the evidence. his current condition is part of the magic. and evidence that there is no use arguing. the MAGIC is always perfect.
