 Question: can you have a heart attack from laughing Context: Gov. Perry also signed H.B. 1815 after passage by the 2007 Legislature, a bill that allows any Texas resident to carry a handgun in the resident's motor vehicle without a CHL or other permit. The bill revised Chapter 46, Section 2 of the Penal Code to state that it is in fact not ``Unlawful Carry of a Weapon'', as defined by the statute, for a person to carry a handgun while in a motor vehicle they own or control, or to carry while heading directly from the person's home to that car. However, lawful carry while in a vehicle requires these four critical qualifiers: (1) the weapon must not be in plain sight (in Texas law, ``plain sight'' and ``concealed'' are mutually exclusive opposing terms); (2) the carrier cannot be involved in criminal activities, other than Class C traffic misdemeanors; (3) the carrier cannot be prohibited by state or federal law from possessing a firearm; and (4) the carrier cannot be a member of a criminal gang.

Dunblane was the UK's first and only school shooting. There has been one spree killing since Dunblane, the Cumbria shootings in June 2010, which involved a shotgun and a .22 caliber rifle, both legally-held. Prior to Dunblane though, there had only been one mass shooting carried out by a civilian in the entire history of Great Britain, which took place in Hungerford on 19 August 1987.

 Question: can a sailboat travel faster than the wind Context: Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons. Protons and neutrons are called nucleons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, that atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively, and it is called an ion.
