Regarding your question concerning the Fast: Travellers are exempt from fasting, but if they want to fast while they are travelling, they are free to do so. You are exempt the whole period of your travel, not just the hours you are in a train or car, etc. If one eats unconsciously during the fasting hours, this is not breaking the Fast as it is an accident. The age limit is 70 years, but if one desires to fast after the age limit is passed, and is strong enough to, one is free to do so. If during the Fast period a person falls ill and is unable to fast, but recovers before the Fast period is over, he can start to fast again and continue until the end. Of course the Fast, as you know, can only be kept during the month set aside for that purpose." (From a letter written on behalf of Shoghi Effendi, ‘Directives from the Guardian’, p. 27)
