(Gizmodo) Think back to when you were a child visiting your grandparent's home. Do you recall a distinct scent when you walked through the door? Many people do and it turns out, it's not just in your head.
Gerontologist and author of A New Wrinkle: What I Learned from Older People Who Never Acted Their Age, Dr. Eric Shapira, says it is difficult to pinpoint the cause or one main reason for the smell; it is a process of what happens to the body as we age. Many studies show that the body's chemistry changes from within as we get older producing a certain scent. Some may describe it as musty. Some may call it stale. Maybe a bit medicinal.
