It depends how long it takes you to shower
8 minutes
It's over 9000!
Dogs usually don't take showers. When their human bathes them, the human decides how long the dog should be in the bath or shower.
You can take one for as long as you want, provided you can stand it and have enough water of the desired temperature and supplies to do so. You won't want to take a very long shower because you'd have a very high water bill. Realistically, a 15 minute shower is usually sufficient.
As long as the woman wishes.
it is not normal... it is gross if you don't take a bath or shower for a long time because you will smell and be gross.
This is a pure rumour! I bet you work at Emirates, a few flight attendant came to me with the same question. There is no problem in take a shower after a flight.
...Seriously?
At the most 13 minutes
Average is probably 5 minutes, but it can depend...
It depends how long you take to shower if you take 5-10 minutes to shower than having a shower is shorter but however if you only take and it usually takes people more than 10 minutes to have cereal so overall id say cereal is longer :)
