Is COVID Why Some People Can't Smell Candles?

The video explores the potential link between negative reviews of scented candles and COVID-19 trends. Researcher Nick Beecham noticed a correlation between bad reviews for Yankee candles and COVID-19 cases, suggesting that loss of smell, a COVID symptom, might be reflected in these reviews. Despite some findings, skepticism remains due to data limitations. Recent trends show an increase in negative reviews, but COVID cases have not risen, possibly due to changes in case tracking methods. The research is not definitive but offers an interesting perspective on disease spread indicators.
