It would be more accurate to say "COVID-19 impacted years" than "incredibly strong correlation between Covid".
A lot of government and public policy changes were quickly made during these times. Are you willing to say with complete certainty that the lockdowns and associated increase in poor mental health had no impact?
We also had global supply chain crunches which affected food and medication availability (among other things). Are you willing to say that having certain brands of prevention / life saving drugs completely unavailable (forcing people to consult doctors for substitutes or go without) had no impact?
