silver,
I am a fit middle aged.
My first brain scan (they place sensors on your scalp)showed problems so i was
sent for an actual MRI.
My brain was obviously fine...thanks god i aint that messed up,the nurse or doctor probably did not set the sensors correctly in the first place!
They found a small kidney stone,in their limit so no issue...try to get this discovered at your local easa GP
I have seen older and large americans working in my airline so they still pass,however not sure how smooth their medical screening go.....
