There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother's body which divides to form. two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form. babies.

People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform. tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity(身份)than to step out of uniform?
Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible(可减税的). They are often more comfortable and more durable than civilian clothes.
