A few years ago all aircraft passengers were scared to the bone by the thought of deep vein thrombosis (DVT). A lot of things were published on what to do to avoid this - from not wearing socks to exercise routines while seated.

But, I can now confirm that the best cure for DVT is to introduce a buffet style service at the front of the aircraft. Why be so lazy as to expect trolley dolly's to serve you at your seat?

Walk to the front of the aircraft to collect your food and drink therefore eliminate DVT forever. Easy.
