Hello nice to meet you all, i thank in advance for any line thread and help provided, i need your advice and wisdom, i was assigned to find some common sayings proverbs and idioms in American English that refers to Age, i am having a rough time finding them, and finding an explanation might not be so complex, the complex part is precisely finding them, things like, "That guy is still a greenhorn" or maybe like "Still a cub to understand" the usage of colors and other references that point to someone's or something's age.

Might sound like a silly assignment at first, but believe me i have found myself in front of a real hard challenge, thanks for your attention, i believe that here with you people i found the experience i need to solve this.
