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

This one is a tricky math question. First of all, you need to think about the duration of one year. In Daily language, we simply say that it is 365 days. But is it? It actually is 365 days and 6 hours. So every 4 years, those 6 ours add upto 24 and “create” a day.

That day, my friends, is February 29th. So let’s get back to our riddle. A person who is 25 years old and has a birthday on February 29th is 100 years old. Because he had a birthday not every year but every four years! So he might be 25 years old but in fact he has lived for 100 years.

**Answer**: He was born on February 29

I still don’t understand
