    Sir... I bow down on ur feet.... If I say I have seen God it is you... The way u explain and give example from day to day life and explaining is very down to earth manner... This work can only be done by Dr Sayd Nazeeb Sir❤🧡💛💚💙💜🤍🤎.... I have completed this video in 3 days by making notes.my teacher gave me an assignment on this topic but i have no idea even what is counter current I don't even know.... But i promice my self that i will see ur video first then I'll write my assignment and it took me 3 days.. Then I read tortora.... By mingling both notes.. I write in fair copy and I submitted LATE.. but i m very happy. I cant estimate my happiness..
    Truely speaking .if I would have power of God I will enhance u to live more then 1000 years.... Take my lifetime too.
    Last but not the least... Say hii to that boy azim😂. He was giving a constipation smile but he is good boy 😁😆.i wish I could sit there and hear ur lecs... But anyway I'll meet u for sure in Pakistan 🇵🇰 1 day for sure...
    I am grateful for your existence. I love ❤😘 you sir.m not a medical student but a biochemist.
