#18 This is actually a pretty good lifehack when it comes to perishable goods. If the store staff are on their toes, they will put the freshest goods at the back so the older food gets sold first. Also the back of the rack will be colder, and any food there is less likely to have been handled by other shoppers.
#20 The penis is no more a memory stick than any other part of the body. It contains as much DNA (on average) except when erect, when it contains a much smaller proportion of DNA because red blood cells and plasma do not contain DNA. If the inference is supposed to be that the sperm carries the DNA, that is only in the penis very briefly. A more accurate simile is that the testicles amount to RAID 0 storage, as each sperm contains half the information needed to make a new person.
