In Japan, /
most people know their blood types, /
so it is easy for them /
to talk about them. /
This is the other reason. /
In other countries, /
many people do not know their blood types. /
In fact, /
they first learn about them /
when they need a blood transfusion. /
If you ask a person /
from the United States or Europe, /
“What’s your blood type?”, /
he or she may say /
“Why do you want to know? /
Are you a doctor? /
Only doctors want to know that.” /
If people do not know their blood types, /
they will not use blood type /
to judge personality. /
