a revelation about tube doors

as I sit here contemplating the amount of physical exercise we will be doing this weekend trekking between the five villages (Cinque Terre) in Italy near Pisa, the muscles in my body are already aching. Admittedly they're a bit sore from going to the gym the other day, but more so because I have discovered something about getting caught between tube doors - it hurts! The doors on the trains here are vastly unlike those back home in australia - the ones back home actually sort of stop and perhaps reopen if you get stuck inbetween them.. not so here. Once the doors start closing, they continue closing, meaning idiots like me who decide to make a runner (cos I couldn't be bothered to wait 2 or so minutes for the next tube) get rammed between them and get squashed. No wonder I'm so sore... :(
