If you are getting into the realms of what is most likely to kill you, then you would also have to factor in the exercise benefit of cycling v the sedentary method of travelling by bus, the risk of catching a communicable disease on an aeroplane, skin cancer risk of lying on a beach in a hot country etc., etc., etc..
Bottom line is, you make your mind up about the risk relative to your desire to do something. I like Greece as a holiday destination. A colleague liked Tunisia as a holiday destination (in fact she's had her October break cancelled by her travel agent and is going elsewhere). But there are lots of other places to go on holiday - many places I've not been that may be even nicer. It's 2 weeks break in the year to recharge my batteries. Where it is isn't all that important, so yes, I'm probably less likely to go somewhere where there is a percieved terrorist risk and more likely to go somewhere where I will feel safer. I'm still getting my holiday, so I'm not altering my behaviour, just choosing a different option.
In saying that, I'd probably avoid Athens at the moment, as there may be political unrest for a few months, but the Greek Islands are probably as safe as most other destinations.
I'd normally avoid the tube in London anyway - too dark and smelly and claustrophobic. In saying that, it's been about 8 years since I was last there.......
