 Question: can you have a heart attack from laughing Context: In the United Kingdom, mobile phone network providers are not obliged to provide unlocking, even after the end of the contract. Ofcom, UK's telecom regulator, allowed 3 UK to sell a mobile phone with the SIM card permanently superglued to the phone. Most operators offer some form of unlocking service, depending on the state of the contract and the model of phone, but usually for a charge. The full Oftel 2002 SIM-lock position paper specifies that there is no SIM-locking law in the UK; the regulator wants only ``consumer awareness''. The examples within the position paper are just ``examples'' of current carrier practices for illustration purposes, but do not reflect any official Oftel regulation. The main networks often agree to unlock handsets for a charge, either at the end of a contract or, for prepaid handsets, after several months. Some Blackberry handsets supplied by Vodafone (e.g., Storm) are examples of a UK carrier not offering unlocking codes. As of April 2011 O will unlock any of their pay-monthly phones for free, even if they're still in contract, with the exception of handsets made exclusively for them, such as their Palm devices. Carphone Warehouse, one of the largest UK phone retailers, offers unlocked phones with most PAYG deals. As of January 1st 2014 all phones sold by 3 UK are unlocked. Phones bought before this date will be unlocked for free.

A small amount of sulfur dioxide (SO ) is added to prevent substance abuse.

 Question: is nos for cars the same as laughing gas Context: In London, John Smith is ambushed by a group of soldiers with a warrant for his arrest and presumed dead in the ensuing confrontation; Governor Ratcliffe has lied to King James (being a personal friend of the King) and framed Smith as the traitor from the first film in a plot to declare war against the Powhatan Nation and get ahold of the gold he still believes them to possess, all while avoiding punishment for his own crimes. In order to prevent this, the King sends a young diplomat, John Rolfe, to bring Chief Powhatan to England for negotiations. In the New World, Pocahontas, Powhatan's daughter, mourns John Smith's death but is eventually able to move on. John Rolfe soon arrives, greeted by English civilians (who by now have settled in Jamestown) and a curious Pocahontas. Rolfe eventually speaks with Powhatan, but he refuses to accompany him to England, so Pocahontas goes in her father's stead, believing that she can bring about peace between the two nations. Powhatan sends a bodyguard, Uttamatomakkin (Uti) to accompany Pocahontas. Rolfe and Pocahontas have a rocky start, but gradually warm up to each other.
