Question:

About guinness world records, are there any issues or conflicts about the records?

please give examples with sources if you have but it's okay even if you don't give the source

Best Answer - Chosen by Asker: Sometimes with records about age, it's hard to verify without the presence of paper work. I know that there have been some conflicts about that, because birth certificates weren't always available back in the day in different countries.

Furthurmore, some other issues involve what qualifies as a category, since what qualifies as a category is completely subjective to Guinness' terms.
