Bluetooth is getting popular. It is very convenient. No doubt about that part.

It might be no problem to use bluetooth keybord or mouse etc. But not headset. It is too close to your brain.

Bluetooth is used radio frequency as 2.4GHz. Microwave is about 10GHz. So it is almost same as you have small microwave on your ear.

Higher frequency is more destructive energy. You can think about infrared ray (IR) &  ultraviolet ray (UV) light. IR is lower frequency of human eye can see. UV is opposit side (high frequency). IR warm up body. UV destroy skin tissue.

Usually it is OK as you are far away. Because it decrease the energy and power are be inversely proportional to the square of the distance. Which means if you make double space, the power decreses 1/8.

That's why bluetooth headset on your ear all the time might be not good idea.

I did not have cellphone 10 years ago. We don't know yet about long time effect. But 2 of my friends got brain surgery in last 2 years.

So I'd recommend to use wired headset.It is your choice.

This is learned from toastmasters friend from Hawaii.

ALOHA means:

  • A (AKAHAI) - (respect)
  • L (LOKAHI) - (cooporation)
  • O (OLOL) - (joy)
  • H (HAAHA) - (humble)
  • A (AHONUI) - (patient)

Hawaii is located between America and Asia. I think these would apply to most of asian countries.But now I think it is apply in US too.

Before I came to US, I thought US people looked not really being "humble". It is from TV show or movies, so I had bias. But I learned more and more about business and successful people.

They have the "humble" in common as well. It might be converted to "appriciation".

Well, I'm still learning these and both US and Japanese cultures.
