If you had listened to your recordings, surely once you think of that is it your real voice? Many of you had even tried to compare other’s real voice and recordings and you get that it is real. Then when it comes to you why does it seem that it is not a real voice? The reason behind this fact is that when we speak we hear our sound in two different ways.

2. Why nails of finger grow faster than the toenails?

All we have nails in the hand as well as in toe fingers. Everybody knows that the nails of the finger grow faster than the nails of the leg, but a few people know the exact reason behind them. Most of you observe it but hardly search for it. Both the fingernails and toenails have a distal matrix below the cuticle which has epithelial cells. This epithelial cell dies and forms keratin which later mixed up with other proteins and fat to form nails. But the difference in both the nails is that there is a proper supply of nutrients and oxygen to the fingernails in respect of the toenails. Along with that covering toes in shoes and socks make it hard to get the proper oxygen. Another reason is that we use our hands for most of the work than our leg. Hence, the growth of epithelial cells is high in hands than in legs, which leads to the growth of fingernails 3 times faster than the toe.
