Ever seen small kids, they make jump despite of small limbs and infant skills. They don't seem afraid of getting hurt or injured. They simply make jump to accomplish what they had to. Sometimes they get injured, even they spend few days in hospital or on bed, but as soon as they walk out or recover they again make such jump just to get it straight.

On other hand, we adults think 10 times even if we have to skip few stair, just to make sure that we don't get hurt ....Kids are more courageous than us .....no??

PS- well, give it a thought who are so much living maturely, and burning their own childishness somewhere..sometime..in some way.  

Maturity is not measured by age but by the way you handle yourself in adverse situations.
