It's important to note that flaccid length does not necessarily correspond to erect length. Some penises grow considerably larger than their flaccid size during an erection; others grow relatively little during an erection. The slang terms "growers" and "showers" refer to penises that grow considerably during erection, and those that grow only a little, respectively.

The thymus atrophies with age -- in youth it is responsible for building up a stockpile of T cells, and it begins to atrophy once it stops production. It then takes on a smaller role of stimulating the immune system -- at birth, the thymus weighs approx 15 grams. During puberty it weighs approx 35 grams. By age 25, it drops down to 25 grams, and by age 60 it weighs a mere 1/2 gram.
