Why the bass?

I've been asked many times why I've chosen to play the bass, being in the back and mostly unheard, while many prefer to play guitar, where you are in the spotlight.
There are many reasons for that,
I play the bass simply because I like the sound it produces. It's a very sexy instrument and you can't shred with it, you have to make people feel the rhythm, everything needs to be balanced, you kind of make a bridge between the beat of the drum and the melody of the guitar. But it can also sound much more aggressive, even more than a distorted guitar, if you just increase the tone and mid/treble. The bass becomes very harsh yet it's perfect for metal. Also, since you don't play chords, headbanging is easier!
People also say that playing the bass is easier than guitar. I can't argue with that, since playing chords on a bass doesn't sound good, and therefore you only play arpeggios. But aside from that, playing bass is the same thing as guitar, and few guitarists who try to compose basslines only play root notes, because they don't know what else to play, or just play it like a guitar and that's just wrong.

So that's basically why I've chosen to play the bass, it's a sexy instrument that is completely different from guitar.
