Heck, with all the alkaloids in tomatoes, tomato juice is more carcinogenic than Rup.  Used to get drenched in the stuff clipping johnson grass heads while dad sprayed, and then years of running and adjusting a rope wick applicator.  Maybe Roundup has kept me healthy.

It was designed as a industrial soap- they accidentally found out it killed weeds even better than it cleaned.  And I have to say, it's a darn good cleaner.  My hand would be spotless after I'd get done emptying that rope wicker.
