  • Perfume in checked baggage, is there any amount limitation?

    Dear all,

    I'm going to travel out of Japan (from Narita airport). I bought quite many perfumes as souvenir and I wonder can I bring them in the checked baggage. If I can, is there any amount limitation?

    Thank you in advance

  • Does fall on your back can cause blindness?

    I've heard that if I fall on my back (e.g. when I do snow-boarding) I can possibly blind because of nerve damage. Is it correct? If it so, could any one please explain what is the mechanism and if possible please give me any link related to this.

    Thank you in advance.

  • Eyes trick on water fall? How does it happen? ?

    I went to see a water fall. One of my friend asked me to see one point in the moving water fall for ten second and directly moved my view on the tree beside the water fall. When I saw the trees beside the water fall (soon after I focused to the water fall), the trees seems to be waving. Almost all of my friends who did that have same experience as mine.

    I wonder why after I see a regularly moving object for a few time, the other un-moving object I see soon after that seems to be moving? Is anyone knows how does it happen?
