A 24-year-old resident from the state of Michigan of USA left hospital to spend Christmas at home with family, where he was waiting his turn to have a heart transplantation. The whole question is that the young man went home without human heart. Instead, he used a mobile device weighing 6,5 kg, Science Daily reports. According to the periodical, such a practice in USA has become widespread in recent years because the queue for heart transplantation is quite large in the country. Due to the wearable technology patients can stay at home and lead normal life while waiting for the operation.

Now scientists work out new devices allowing people to spend less time in hospitals.
