et resera nutu candida templa tuo.
If you want to be a representative of a constituency and sit in the House of Commons then you need to not sleep on the job. If you feel yourself falling asleep, go to the loo and walk it off. If you can't be arsed to do that and would prefer to fall asleep in the House then resign.
That would not be a good idea in a 7.5 tonne vehicle. I can understand getting some shuteye on your dinner break or such but when it comes to representitive and or safety critical roles and it's not in your break time then I imagine it would be classed at the very least as negligence.
