Dr Campbell eats education for breakfast! Ur the man!😎

This really help us the nursing students around the 🌍...  Thank you Dr John for the powerful presentation🇿🇲🇿🇲🇿🇲

Hi John you looked so young in this video. Was it your younger brother?  Just wanted to say I've been following your covid updates and advice.  Been taking my vitamin D3 and other vitamins and nutrients.  Keep up the great work and good advice...  many thanks.

I love these old lectures, John. Very well presented. I feel like I’m back at Uni lol

Good old Dr. John)
Could you ever imagine becoming so popular after Coronavirus pandemic?

Dr John, I've been following your videos all through the Pandemic. Now I have a heart arrhythmia & I'm doing some revision in order to better understand my condition ( it's been a very long time since I retired from nursing!). I was looking at a cardiology presentation, & then spotted your videos...amazed to see the much younger you, talking about blood pressure. I knew you are a good teacher, but this video conformed it! Thank you for the way you make the complicated better understood!

Browsing after seeing your coronavirus videos. All good stuff.

This video must be a good 15-18 years ago. No one ages that much in 5 years!!!!

Then, now....  so handsome AND smart.  :)  Thanks for all you do here, for all of us Dr. John! :)   Stay safe & be well.

Ahead of the curve doctor, before YouTube was even a bad thought. I've been watching you since end of January. Keep up the great work  you are quite impressive. I salute your hard work you great explanation and prediction of current events not too many of your kind left. Best of luck, I look forward to your tomorrow's video

OK Dr John, hand over the youth serum :)

This video is way over 5 yeas old. Looks like it was made with VHS.

You can now get all of the current videos and podcasts on a 64 Gig flash drive. About 420 video files and 100 podcasts. You can order one from campbellteaching.co.uk This saves ordering individual disks, its all on the one flashdrive. Best wishes, John

Thanks Dr. John, very informative, I have high BP it's nice to know how it works.

This was in my recommendations... holy sh*t. Hi John, you look to be around my age now maybe a little younger. Still so handsome :)))
