A recent e-mail detailed at disgusting length the health hazards of travelling to work on the London Underground.
But on reaching work, do not heave a giant sigh of relief - your working environment probably poses an even greater risk.
First there is the general penicillin/food bugs issue.
Hands up anybody who has never left a cup on their desk to develop an amazing culture or, even worse, forgotten some succulent item in their desk drawer for several weeks. Add to this the contents of the fridge that would delight an expert in cheese production, and those foreign treats brought back by a colleague and never quite finished, and you will realise this is not a centre of food hygiene. Then you complain about a stomach upset and blame the sandwich, rather than the desk from which you ate it.
If your practice is fairly impecunious it is not going to waste money on fancy furnishings. But this could translate itself into curling carpet tiles and unstable chairs, which could result in nasty falls.However, fame can be equally dangerous.My friend Ellen has still not completely recovered from the time she fell over the trailing cables of the visiting television crew.
Then there are your colleagues - a dedicated bunch. Come into the office, well or ill - and bring all their revolting diseases with them.
If they suffer from anything airborne, don't imagine you will escape. And then, of course, you will struggle into the office with the selfsame germs, kindly passing them on.
If all this is depressing you, you may want to pack up early and go for a consoling drink with your colleagues. Just remember - alcohol is definitely bad for the health.
