Also sharing some thought about the apparent issue with publishing with Elsevier and special issue.......of course I would love to submit to Non-Elsevier, but there are not much sleep x circadian journals out there: Journal Biological Rhythm was my original thought but they are less sleep and our work did not address any circadian issue..there is a new kid: npj BTS...but npj is not less evil.. Also this NBSCR special topic was called by Stuart Peirson and very fitting to what we do
