>The effect of castration on lifespan

I have just finished reading Mean Genes, an entertaining book that 
describes itself as an owner manual to our bodies and brains. One of the 
claims that it makes is that when castration was used for some criminals in 
the early 1900s, it lengthened the average lifespan of the criminal by 15 
years.
