don't listen to people saying you are too old. I am 46yo now unloading trucks and that's all I want to do. I like dishing out the punishment!
I can completely dictate when I leave for the day. I work my butt off, to get the work done, so I can leave.
I have a full-time job and work at UPS for the spare change and the full-time benefits.
I am also the one of best unloader at my location with a PPH of 1575. I kick these little 18-25yo punks butts, they whine, complain, take frequent breaks, throw up, give up, quit...etc.. and I am old enough to be there daddy!
So don't listen to anyone, when they tell you are too old at 48.
