The racks-you didn't call them beds-were not known for comfort but after being awake and Working for anywhere from 24 to 51 hours you really did not care bout comfort at that point. And in the case of the older Ship I was Serving on-U S S Yorktown C V S-10-the sea water evaporators were not very efficient in warm water. Sometimes you rinsed the soap from your shower off with salt water. NOT a fun deal when it's over 100 degrees F with 80 to 90% humidity. Even though tired I looked forward to flying. Hotter and sweatier-survival gear over a flight suit and a helmet and very heavy hot boots-but sometimes I could catch a nap of 35 minutes to an hour before we got to our patrol station. IF my heart and lungs could stand it would Not mind running up and down the ladders tween decks again. I could stand to lose bout 25 pounds or so.

Had an old Chief-E 8-tell me-you ain't on a luxury liner boy this Be a United States Navy ManOWar. And I Never forgot that. Battle Ships Carriers Destroyers Cruisers Submarines Military Air Craft are All designed to kill other military vehicles and the people that man them. You do NOT wanna be on the receiving end of those 16 inch Naval Rifles. Wonder how long it would take to spool up an old Battle Ship and train crews to operate again if they are ever needed? RIDE SAFE.
I toured the Yorktown several years ago.
I don't remember having to climb any ladders as part of the tour, I do remember some pretty steep stairs though.
The climbing wasn't bad but I wasn't trying to run them either.
I do remember saying to my wife that there's a good reason why the average age of a sailor is 19 yrs old.
