Wait, so why're they careful with this one? I get that the implication is that major world powers would try to obtain it if information is leaked, but this is hardly the only SCP to grant powerful boons to humans. It's also not at all uncommon for the SCP foundation to utilize useful SCPs in order to contain more dangerous ones
I like the switcharoo they pull on us, but a fountain of youth is honestly not a big enough deal by SCP standards to warrant that treatment
