Brit with an inquisitive mind from as far back as I can remember. Red-pilled since 9/11 been searching for truth(s) ever since.
The absence of flu can be explained with the concept of similar and dissimilar diseases (200-year-old core theory used by homeopaths—look it up in Hahnemann’s The Organon Of Medicine) which either complement each other or aggravate each other. My understanding of the situation is that there is no flu this year because it is similar to covid and therefore displaced by it.
