I like drinking coffee, I do that at work. A nice big stretch from time to time is great, I do at least one each day at my desk. Several times each week I'll take off my glasses and rub my eyes a bit, I don't care who's around!
Sure, there are things you like to do that shouldn't be done at work, but the two are not correlated--or at least not as correlated as you suggest. While you've found some very amusing examples, they're tangentially relevant at best and used more for hyperbole, just like most of the article.
