The Zanotto's. Possibly the tallest people in the school.
Possibly the most at danger.
Cancer. As you know, a very deadly disease. And as you also know being taller means you have more surface area.
Not only this, but cancer is caused by UV rays, which, of course, impacts you more if you have more surface areas.
Personally, i would like to extend my sorrows to Mrs Zanotto, who will outlive her husband by a while.
