It works the other way around too. My wife passed away in 1996 and I couldn't bring myself to get rid of any of her things. Last fall my sister put her foot down and told me 10 years was way too long to be holding onto that stuff. Of course, she was right. So, the next weeked we went down to my basement to deal with the stuff. When I opened the first box of clothes - that smell, wow! It just floored me. My sister saw the expression on my face, told me to go upstairs and she would handle things. An unbelievably powerful effect a decade later. Just amazing.
