Ramadan is conducive to my health

I may as well say this as think it. Ramadan is conducive to my health - shall I elaborate? Why not, then maybe you might understand. I have just travelled home in a taxi, where the driver was nearly falling asleep at the wheel. He told me he had been on for a 12 hour shift with no food or fluids during this time! I feel that due to this unhealthy religious diet Ramadan, he was worn out and basically uncohererant due to lack of fluids and food. Therefore, all taxi drivers on Ramadan should be restricted to limited hours. I totally respect their religion but would like to get home in one piece!
