No regrets in retiring, still it's an odd feeling to leave a place where you spent so many years of your life. I'll go back out there next Tuesday for my retirement party and eat some pizza and cake, then be escorted back through the gate where they take my pass. Now I can stop worrying about being burned from acid, steam, condensate, chlorinated by-products and caustic soda. Or falling down stairs and having to climb distillation columns or up in piperacks. No more permits to fill out or having to do lockout/tagouts for maintenance work. Not going to miss that at all.
