How does your name taste? The strange science of synaesthesia

Constantina Makridakis, a 28-year-old jewelry designer from Greece, discovered she has a form of synesthesia where names and voices trigger taste sensations. For instance, her father's name, Nicholas, tasted like caramel-coated chocolate. Synesthesia can manifest in various ways, such as with Billie Eilish, who associates days of the week with colors. Approximately 2 to 4 percent of the global population may experience some form of synesthesia, although many do not realize it.
