Interesting post - it has been discussed here before here about whether ADHD or something similar is abundent in the top guys. The pendantic (OCD type) lifestyle needed to follow every rule for eating, sleeping, training etc etc. and that's without the weeks spent on mountain tops away from family and friends. Vingegaard's problems are well known, but nothing about Pogacar (unless you know different?!).
TUE's for all manner of stimulants (immediate and extended release forms) are WADA allowed so, like the recent past, when every man and his dog suddenly got asthma, we might see a sudden increase in "neurodiversity".
