Get your vaccination records!

does anyone know if having hernias can cause a problem with passing the medical and also I am overweight will they make anything of it?
If our jabs are all up to date do they still do a blood test?
And no my dear friend, being overweight is no reason for denial so don't give that much thought, ok?
