I am sorry, but you are factually wrong. Some part of it Enigma answered. I can bet, when he said he/his super model daughter, the criminal Maryam Bhagori said he had 4 bypasses, he didn't had any.
Apart from his physical condition and movement within days of his alleged bypass he was coming down the stairs of the hospital without assistance. Around same time one of my family friend and neighbor had bypasses. He still cannot move freely after over 2 years. If you see his face, you can see he is extremely ill.
While Nawaz is not ill.
I have repeatedly written if you take sample of the population in Europe and USA, may be over 20% to 30% of the older generation lives with angina pain. This is nothing especial. similarly the hypertension and plaque is a very frequent occurrence in elderly people, nothing extra ordinary.
In short this man is as healthy as any 70 years old could be in Europe or USA.
He should be sent back to the jail to do time for his crimes, period.
