[1]The Wall Street Journal [2] recently reported on the science behind successful long-term relationships. Using brain scans and MRIs, researchers are investigating those who are just as giddy about their significant others 20 years into the relationship as they were at 2 months.

When showed images of their spouses, participants’ scans showed a strong reaction in the ventral pallidum, an area suspected to have links with long-term bonds. The subjects apparently enjoyed old love just as much as new.

The studies could dissect lifelong passion and even one day “lead to a restorative.” As in, bringing back that lovin’ feeling. Divorce lawyers—instead of silver anniversaries—might eventually be on the endangered list!
