Music.

I listen to music literally all the time, and this helps my well being in many ways, it helps express my emotions, and remembering certain things. It sometimes makes me more depressed than I already am how funny.

Music can increase our mood either if we're sad then it'll go up a bit.
You can relate to your music taste or the lyrics emotionally or mentally. Whatever floats ya boat swoosh swoosh. Music can also help you sleep, study, remember. Something along those lines ya know. It can keep you on track. so funny
Sometimes it decreases your mood, even if your sad. It makes you more sad, so depressing oh no.

It increases  your IQ  apparently.
Thanks bye. Listen to music it's amazing
