Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?

They do not possess flesh or feathers or scales or bone
But still, they are blessed with fingers and thumbs of their own.

My thunder comes before the lightning; my lightning comes before clouds; my rain dries all the land it touches. What am I?

How can you write nineteen in a manner that if we take out one, it becomes twenty?

Begin with a word, five letters to my name,
Remove the first and last but I am the same
Take out my middle and still, I remain.
What word am I?

Give it food and it will live; give it water and it will die.

OF DRY FENNEL FOR DINNER FOR

What breaks yet never falls, and what falls yet never breaks?

I have a head like a cat and feet like a cat, but I am not a cat. What am I?
