What am I

I was teaching policy analysis this afternoon and developed a wee activity on "framing" of policy issues. I'll repeat it here - it's just a series of statements about a mythical "something". A smug feeling of satisfaction to the first person who can guess what it is:

• It killed 3,409 people in 2000 and this fell to 1,713 in the UK in 2014
• In 2014 it injured 192,000 people in UK, 22,807 of them seriously
• In 2012-13 there was a 12% increase in the number of the most vulnerable people in the UK killed by this.
• WHO estimates it kills approximately 1.24 million people worldwide a year.
• Not doing this and doing something else can add 3-7 years to your life expectancy.
• Not doing this and doing something else can add six months to your life expectancy.
