The weight of a person should be proportionate to the height. But if it increases beyond something considered normal then it is a risk for the person. Hence it is very important to monitor day to day weight and bathroom scales are the best way to do it. While weighing oneself it is important to stand straight and look in front but when you are doing it all yourself it is difficult to do it in this way because you will have to bend to know the weight and this probably can give you wrong results.
However My Weigh has come up with talking bathroom scales called “The Phoenix” which is a solution to this problem because with this is place you will be now no more required to bend to know your weight because it can read your weight. It is the first of its kind and speaks in clear unaccented American English. It uses strain gauge technology which gives it precise results.
