One must be careful of what a statistic is actually showing or indicating. For instance, the average age of death is not an indicator of when adults are dying, rather it is an indicator of child mortality (an average age of 30 years means lots of kids are dying, pulling down the average). Likewise, an increase or decrease in a type of crime (or other social phenomenon) may actually be nothing more than an indicator of population changes. And as one person has already suggested, the increase in knife attackes in the UK may be nothing more than better reporting.
By the way, why are doctors against knifes? Itsn't the injuries good for business? Just joking.
