Sonny Bill Williams shares photo of his blood-sucking detox treatment

Sonny Bill Williams seems like an interesting bloke.

Not many people would give away their World Cup winners medal, but he did.

There must be a lot of stress involved in being so damn talented, as evidenced by the lengths Williams will apparently go to in order to detox and refresh himself. https://twitter.com/SonnyBWilliams/status/669313610384932864 The practice of drawing out blood using pressure cups - commonly known as hijama - is not thought to carry any medical benefits, but is a therapeutic procedure used in Islam as a way of removing toxins from the body.
