Hmmm... I can understand your cousins' behaviors. They have a lot to lose that's why they are afraid of dying. They probably have to consider the future of their young children if they die of sudden premature death. Also, some still have plenty of unfulfilled dreams. The best action is actually to prepare wills first instead of rushing off for COVID jabs. For those with crypto assets, it's best to let their spouse/trusted kin know the whereabouts of their private keys prior to getting COVID jabs.
Smart singers and film stars got involved or collaborated with Youtube and Netflix. Their futures are somewhat secured for the time being. That is if Youtube and Netflix kept their words and reward them accordingly.
