No piercing is considered fully healed until it's a year old. Contrary to what you may read, it takes the body a full year to season a piercing to the point where it can be removed for extended periods of time without the risk of the piercing closing.
HBr is polar. The Lewis structure shows a central carbon atom forming four single covalent bonds with the four terminal bromines. The central carbon has no lone pairs and four bonding pairs, so the molecular geometry is tetrahedral (as is the electron geometry), and bond angles are thus approximately 109.5 degrees.
The water molecule is bent molecular geometry because the lone electron pairs, although still exerting influence on the shape, are invisible when looking at molecular geometry. The molecule is two dimensional and bent as opposed to the beryllium hydride case which was a linear or straight line molecular geometry because it did not have a lone electron pair.
