(WHAS11) -- A study by researchers in Philadelphia and Sweden finds people over 75 smell the best.
Study participants smelled three different age groups: 20 to 30, 45 to 55 and 75 to 95.
Researchers say our body odor goes through several stages as we age and they wanted to see if people could identify age based on scent.
Participants could only tell the seniors' smells distinctly. The study is published in the journal "Plus One."
