A story on NPR this morning about synesthesia and synesthetes got me to wondering whether sun sneezing is simply a more common form of synæsthesia (I’m varying the spelling to attract more search engine traffic). So, if you’re a synesthete, please drop me a line and let me know whether you also sneeze in bright (or dim) sunlight. I won’t do anything with your email address except possibly ask a follow-up question. Nothing personally identifiable will be published in my summary of results.
