Instant Chemistry is a new test that helps match singles, and assess couples' likelihood of staying together for the long haul, by analyzing the DNA from your saliva. Here's how it works for couples who want to put their romance to the test: You and your partner order the kit, spit into your respective tubes and mail them in. There's also an online personality test to take. Then, just sit back and wait for your compatibility score based on physical, emotional and psychological factors. Back in the lab, Instant Chemistry's team of scientists is looking at genes associated with your immune system and emotional processing. It's all based on recent studies that examine the correlation between partners' immune systems and their sexual satisfaction, level of attraction, fidelity, fertility and children's health. Instant Chemistry's scores are based on the idea that the less similar a couple's immune systems, the better their relationship may fare. The test also considers research on the serotonin transporter gene, which looks at the relationship between emotional behavior and changes in marital satisfaction over time. There are two versions of this gene. The long version may help you maintain a more level head in emotional situations, while … Continue reading →
