How many points are there on the globe where, by walking one mile south, then one mile east and then one mile north, you would reach the place where you started?
I am 5 letters long.
My first two tell you who I am
My first 3 could be a medicine
My last three reversed could be a young boy.
My 4th, 3rd and 2nd in that order could be a fruit drink.
If you have me you may hang me round your neck
WHAT AM I ?
