Gitar, i have done some research over the years and have found a potential problem with mobile phones and the human brain. Can you do me a favor? Shut the phone completely off when you sleep and wrap it up in aluminum foil because the foil acts as a barrier to prevent the phone from transmitting. Furthermore please only use speakerphone or corded headset and keep phone away from your head and body as much as possible. I will be telling my other Thai friends also about this. Even though i am new to you, i genuinly care about Gitar. Smartphone can be dangerous to human health.
Thank you Gitar.
