Hi,I’ve been using a macbook pro on a daily basis for the past 10 years or so.
For the past 3 years or so, I’ve been using it constantly plugged in (charging) without an external keyboard/mouse.
This period closely matches up with the period I’ve been having heart palpitations.I’m an otherwise healthy individual, 28 years old, no previous conditions, athletic body. 
I go running 2x a week, and have a set of bodyweight exercises I perform DAILY, to keep in shape.
I have never smoked or had any relatives with heart issues.I recently quit caffeine completely, since I was having more and more palpitations daily.
The symptoms have improved, but not disappeared.Today, when my girlfriend came to pat me on my arm, she saidher: “Wow are you cold?”
me: “No, why?”
her: “You’re shivering” 
me: “Ah, no that’s because, I’m touching my laptop. I have an electric current traveling through me.”
her: “OMG???”And that’s when it hit me: I’m constantly being electrocuted on a daily basis by my laptop.
I’ve grown accustomed to the small current that’s traveling through my body for at least 8 hours a day.
I even adjusted my sitting posture, so that I’m always in full contact with my laptop, in order to avoid a partial contact (to avoid THAT painful sting).I know that many of you know about this constant weird buzz, when for example You gently run a finger over your macbook, whilst it’s charging.It can’t be healthy… right???Are any of YOU experiencing similar symptoms or are in a similar situation?Do You know of any research on effects of small current on the human body, over a prolonged period? (unlikely)Are any of You encountering anxiety, tension in chest, near the heart ?
