Long time no see Vendome -- glad to see you back.
I've seen numerous of this type of list before, and unless someone wants to take some serious time in researching the answers, I say they are all up for scrutinizing. I did a quick check on the goldfish thing and found
this article from 2003 showing research and goldfish memories. However, it is from a newspaper,and I don't necessarily believe everything I read in a newspaper

. So, take it or leave it, your choice.
I suppose when one googles one of the items and find over 15,000 hits just in question and answer forums it is definItely up for debate.
