She is a leading expert on the biology of love and attraction.[5][failed verification] Fisher said that when she began researching for her dissertation, she considered the one thing all humans have in common – their reproductive strategies.[6] She is now the most referenced scholar in the love research community.[citation needed] In 2005, she was hired by match.com to help build chemistry.com, which used her research and experience to create both hormone-based and personality-based matching systems. Fisher advises that in order to sustain long-term deep attachment and romantic love, a couple should leverage neurochemistry by regularly having sex and physical contact (which drives up the oxytocin system), engaging in novel activities (which drives up the dopamine system), and saying nice things to the partner (which reduces cortisol and cholesterol).[10] ^ "Helen Fisher – Love and Sex and Attachment". ./cache/en-wikipedia-org-6330.html ./txt/en-wikipedia-org-6330.txt
