Now this is what is real tech serving humanity. the situation in public hospitals in the 3rd world/developing countries is worst. Just imagine about a situation where patients visit hospitals for heart surgeries and they have to bring their own cots as no beds are available in the hospital except a very small no. So how they would be treating the patients regardless of whether are operated or not specially carrying one bed (that's in this case patient's own cot) to the bed of hospital in a carefree way. There is no doubt in the brilliance of this great product and I'm fully in love with it. Good job Hive account@badmusgreene. I'm just giving my input on the distance between the most advanced products and broad ignored audience that will never get benefited from it even after next one decade.
