Alright everybody, this time I looked specifically for hard riddles, so hopefully this one will not be a cakewalk. Let's go!
#1: I am something people love or hate. I change peoples appearances and thoughts. If a person takes care of themself I will go up even higher. To some people, I will fool them. To others, I am a mystery. Some people might want to try and hide me but I will show. No matter how hard people try I will never go down. What am I?
#2: Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?
#3: Who is that with a neck and no head, two arms and no hands? What is it?
#4: If eleven plus two equals one, what does nine plus five equal?
#5: Can you write down eight eights so that they add up to one thousand?
#6: What English word retains the same pronunciation, even after you take away four of its five letters?
#7: What is it that given one, you'll have either two or none?
Have fun solving these ones!
