I'm going through 6 weeks of training now. I guess I got a little spoiled over the last 20 years of being home every night and a nice hot shower/normal life. But I served 4 years in the United States Marine Corps when I was a kid and once went 22 days without a shower lol.
Just like riding a bike! My trainer takes a shower once a week whether he needs it or not, me, I do the 'canteen' wash to create the illusion I'm not filthy at the shippers/receivers.
I was afraid after I had spent $5k I would get out here and hate this lifestyle but I'm really getting into it now. It's excited to get loads on the qualcom for me, I feel needed after 15 months of being out of work.
