A man dies of old age on his 25 birthday. How is this possible?

 

He was born on February 29th?

 

She's as smart as all get out.
I was a touch slow on this.. please explain.

 

Craig, how can you be slow on something that you yourself posted?
I'm definitely one of Shirley's admirers! Intimidatingly smart she is.

Isn't the answer obvious once you have his birthday? Since the 29 Feb. is only every four years, this guy may have died aged 100.

 

You can hold me in your right hand but you can't hold me in your left hand.

 

Yep. I did not know that when i posted it. Or rather I had forgotten that Feb 29 was a Leap Year day.

 

Your right thumb?

 

Your left thumb?

 

Close enough...... your left hand.

Next.....

 

What runs but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps?

When you stop and look, you can always see me. If you try to touch, you cannot feel me. I cannot move, but as you near me, I will move away from you.

 

1- river
2-shadow?

 

You got first one.
