Of course you should have breaks, any fool kno (as Molesworth would have said) that people who work for hours without a break get TIRED, being TIRED makes you careless however careful you try to be. It is COMMON SENSE. That is sadly very uncommon these days. Getting TIRED regularly can also make you ill, you become vulnerable to any bugs that are going around, vulnerable to accidents and vulnerable to depressive illness which can make it impossible for you to work again EVER. Is there any way that you can get that FOOL journalist to ride with you for a month - minimum. Probably no point, the Sun never was interested in reality. Look after yourself.
