If the interior arrangements worked okay in 1938, don't change it!

As you perhaps know, both Londoners and tourists are taller and
weightier than in 1938.

Tom Stewart, managing director of ergonomics consultants System
Concepts, says that while obesity is a growing problem, healthy Britons
are becoming larger too.

"People are generally bigger than they were. A poor diet used to mean
people didn't reach their full potential size. Improved nutrition has
changed that."



I'm not sure that this explains why the seats keep getting smaller
though.

In any case, the change in average size of person since 1938 must be
trivial in comparison with the range of actual sizes either then or now.
