How long do you think ACDC is going to keep doing concerts?

Hey everyone!

I really want to go to an ACDC concert, they're fucking amazing and it's my favorite band, but I'm just 16, so I doubt I can go alone and I don't think my parents would let me go alone/take me to a bigger city where the concert is.

So my plan was to wait till I'm older, maybe 18 maybe 20 and maybe with a couple of friends, I don't know, and go to Barcelona/Madrid, where there're often concerts, since they're bigger than where I live

Do you think they'll do more concerts for some more years? I don't really know when it's all going to end, they're 60-70 and probably super tired. And I'td be horrible not to go to one.

Thank you very much
