Nurse is quite a in-demand job nowadays, It can be a lucrative job too if one gets to practice his or her profession in other countries because they would be earning in dollars,pounds,dinars or even in euro. Personally I am amazed by the work of a nurse because they always have shifting work schedules and you should really have the patience and courage to deal with different patients.
I am not really sure why does the nurse wear a scrubs, but for me I kind of liked it. I remember there was a time when it became popular and I see a lot of people wearing a scrubs top, although I don't they are really a nurse or they just like wearing it.
By the way, I came upon a manufacturer of these uniform in the internet that sells cheap scrubs and yet with highest standards of quality and they also has a large variety of colors to choose from. They have sizes for men, women and even for children. They have different styles as well, from simple to urban and you can have it custom made too. They also offers free shipping for certain orders and also gives certain discounts. I know about this because I have a cousin who is a personal nurse just ordered and she already got it just in time, and I am just happy for her.
