I already give my private key into my sister. Just in case, if something bad happen to me then she can still access my wallet. My sister is investing in cryptocurrency too, so we both know about the private key.
That was a good decision to make, because we don't know what the future holds for us. Another thing important is giving your private keys to a well trusted person, someone who understands Cryptocurrencies and how it works. I think is important we tell our family members the details of our Wallet(s), so, our coins won't be gone forever, if something bad happens. Because, is impossible for someone to have access to your wallet without the private keys.
Indeed a good decision, whatever happen to you the assets that you have will continue to exist.
We have to deal with realities that no one knows how long we will continue to live, death is just there awaiting and in any moment it
will come and take us with it, moving back to the topic, without those private keys and knowledge to the person who you entrust the
information, those coins will be unuseful and no one will able to use it anymore.
