Ep. 21 - The Science of Cheating: Love, Lust & Spit Tests with Dawn Maslar-Biggie

What if the key to understanding love, lust, and infidelity lies not in your heart—but in your hormones? In this episode of Dateless in Delray, Susan Heller Shoer sits down with science writer and “Love Biologist” Dawn Maslar-Biggie to explore the biological forces behind why we fall in love, why we stray, and how spit tests might one day predict compatibility. From oxytocin and dopamine to evolutionary instincts and modern romance, this eye-opening conversation blends humor, science, and insight to help you date smarter—and maybe avoid a broken heart. Love may be messy, but biology has a blueprint.
