Ummm... Maybe that is just a one off but well licking Actinium [Ac] (Z=89) is really a very bad idea.

There are no stable isotopes of this element so best case you lick an alpha emitter with about 22 years of half-life so killing you more/less slowly or else...

You will die pretty soon from the other isotopes emitting multiple particles and especially alphas.

But yeah maybe that is just one wrong one, rest will be fine, pretty sure 😅👍
