normally the worms live on average 18 and the top $28.00 days but the ones with the additional free radicals didn't die young on the contrary they lived on average $21.00 days even up to $35.00 days and that's not at all what the researchers expected. ready in a 2nd round of experiments the worms also receive the chemical promoting the production of free radicals but this time they were given vitamin c. and c. as well so called antioxidants which scavenge free radicals again the lifespan of the test subjects was carefully recorded. the result was that those worms only lived an average of 18 days the last ones were dead by 26 days. but you can see you know we are observing that these free radicals were responsible for the worms living longer and when we removed the free radicals the
