Most men find that one testicle is slightly bigger than the other or hangs lower than the other. Usually, it is the left testicle that hangs lower (though the right testicle may be larger), as a result of fetal development. In most cases, testicular size has nothing to do with a manâs fertility or his sexual function, and slight differences in testicular size are not cause for concern.
Showering to Savings. In an average home, showers are typically the third largest water use after toilets and clothes washers. The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).
Switch to a Low-Flow Shower Head. Low-flow shower heads use 2.5 gallons per minute (gpm); older models use as much as 5.5 gpm. Make the switch and you'll reduce your water bill by 25-60% (US Department of Energy). How to Install a Shower Head.
