I know this paper has come up before, but here's a nice explanation of the problems with it.

The paper shows that male rats drinking pure water will have a 50% higher mortality rate than those drinking water contaminated with 0.5% Roundup herbicide. Unlike the other graphs in which the results don’t make sense (for example, more male rats die eating 11% GM-maize and sooner than those fed 0%, 22% and 33%), there is a clear correlation between the amount of Roundup herbicide consumed and life expectancies. Rats drinking water contaminated with 1.1×10-8% had a 11% less mortality rate, 0.09% contamination had a 22% less mortality rate and 0.5% contamination had a 33% less mortality rate. If this paper is correct then the more herbicide you drink, the longer you would live.
