The sign for "experience" is based on the idea of stroking a beard.
The version of the sign I'm doing below shows a somewhat exaggerated movement. (Pulling the sign down further than normal.) The more you exaggerate this sign indicates more experience.
EXPERIENCE:
Memory aid: Think of an old man with a white beard stroking the beard as he reflects on his life experience to solve some sort of problem. Older people have a lot of experience.
Note: If you see someone do the sign "EXPERIENCE" using a criss-cross pattern (down as normal and then doing a crosswise forward stroke (the flat of the fingernails are dragged across the cheek toward the front) it means "very familiar with."
Notes:
