@Jenny_1884 The cause is you. It’s your own cells not playing nicely, which is why it’s hard to treat. Most people used to die of other things, but has been with humans and animals for millennia. Main causes are roughy bad luck, followed by age and then things like smoking and drinking.
@robinmonotti No scam. Vaccines save millions of lives at low cost. Climate change already ruining lives. Clearly you have a vested interest in denying the proven.
