It shuts off the part oif the brain linked with bad thoughts and memories

You scratch an itch! An itch itches. You scratch an itch to remove the pain.
An itch is something that makes you want to scratch
Cause it feels good!
Scratch That Itch was created in 1990.
The act of agitating the skin as to relieve a sensation or irritation is called scratching. Thusly, you would need to "scratch an itch". It is physically impossible to "itch a scratch", no matter how hard you try.
Because itch and scratch go hand in hand and everyone gets scratching an itch confused with itching a scratch.
Scratch
you scratch it.
Scratch
Scratch it.
