Hi, I'm a 20 year old male. About two weeks ago I noticed a faint darkness on the top of my hand right above my knuckles. They look like two brown circles one the size of a dime and the other the size of a nickel. The spots grew slightly darker in the last week and now are really noticeable. ...

Hi Please help me! I have noticed a lot of brown small spot on top of my hand overnight. It's not itching or hurt. I am very nervous because I don't have medical insurance and I can not afford to do private pay to see a doctor. Is this a skin cancer? Please reply. Thanks a million!

I have seen on Tv and movies that many in the West eat with their left hands. Is this recommended practice or not? I am curious because we specifically use the right hand to eat as the left hand is used for cleaning after going to the bathroom. Thanks in advance:)

What is the difference in a horizontal left hand or horizontal right hand application as far as an air handler? Also, which end would be the return and/or supply? The "a" coil is at one end and the blower motor is at the other end. Thanks
