medical check-up

I am going to have a medical check-up tomorrow. I hate to swallow barium. I feel depressed when I guess a medical check-up.
By the way, I was surprised to hear that my body height was 166cm last year because I recognized my body height was 164.5cm. Recently the physical size of young people becomes bigger. That's true but I am too tall to wear a pair of heeled sandals in Japan. I wonder if I go to live in somewhere...
