How long do VHS tapes last before they deteriorate?

Something that warms my heart just a little is that there’s been a resurgence of interest in physical media. For some people it’s about going retro, reliving an imagined golden age. Others just like collecting obscure releases. One thing everyone can agree on is that it’s nice accumulating media that’s truly yours, and won’t disappear the second you can’t afford a subscription, or the service you’re using loses the streaming rights.
