The Law of Abstinence obliges those 14 years of age and older to not eat meat.
The Law of Fast obliges all those from ages 18 through 59 to refrain their eating to one full meal and two lighter meals for the day. The other two meals, sufficient to maintain strength, may be taken according to each person's needs, but together they should not equal another full meal. Liquids are permitted between meals. When health or ability to work would be seriously affected, the law does not oblige. Ash Wednesday and Good Friday are days of both Fast and Abstinence. Also, in the United States, all Fridays of Lent are days of abstinence (no meat).
Disposal of Palms
Because they have been blessed by a priest and therefore are holy objects, the palm branches used for Catholic Church services, especially those used on Palm Sunday, should not be disposed of in the regular fashion. Once an object is blessed, it is considered to be in the service of God and should be treated with respect. Therefore, it is considered sacrilegious to throw a holy item in the garbage, where it might end up in a sewer or a landfill. Holy palms should be returned to nature. Should you wish to dispose of it, you may bury it or burn it and spread the ashes outside.
