Thanks for reading my profile 🙂

So Geneva is full of banks, and every country store their money in Swiss banks, much of which is stored in underground vaults. Now the Large Hadron collider is also there, which collides fast moving protons underground. There you go! But the subtext is, earth is being bombarded by cosmic ray every moment, and there are high energy particles passing through your body, without you knowing it 😉
