As we get older our bodies change - now science has confirmed that so does our odour!
The study looked into the thing commonly referred to as 'old people smell'.
The results found that it is a real thing! The older we get, we tend to excrete a certain type of odour.
"The body odour of subjects between the ages of 26 and 75 was analyzed by headspace gas chromatography/mass spectrometry." the study said.
"2-Nonenal, an unsaturated aldehyde with an unpleasant greasy and grassy odor, was detected only in older subjects (40 y or older)."
"Furthermore, analysis of skin surface lipids revealed that unsaturated fatty acids and lipid peroxides also increased with aging and that there were positive correlations between the amount of 2-nonenal in body odor and the amount of unsaturated fatty acids or lipid peroxides in skin surface lipids."
"The results indicate that 2-nonenal is generated by the oxidative degradation of unsaturated fatty acids, and suggest that 2-nonenal may be involved in the age-related change of body odour."
So next time you think you might be able to smell it, be kind - it's just a part of life!
