Are there any rules for Lent?

Some obligations during the Lenten season change between the Orthodox Church and the Catholic Church. For the Roman Catholic Church, some obligations for practicing Catholics over the age of 14 include abstaining from warmblooded meat, such as beef, poultry, ect. but other meat such as fish is still allowed. Also the is an obligation to fast on Ash Wednesday and Good Friday. The Catholic notion of fasting is eating one full meal (10 oz.) and 2 small meals not to exceed the full meal. As every other Sunday of the year, it is an obligation to attend mass every Sunday during lent including Easter Sunday. Ash Wednesday is not a Holy Day of Obligation but is often attended. People also either vow to give up something or do something in order to make themselves closer to God for the 40 days of lent (every day minus Sundays. Sundays are not included because they are a joyous day celebrating Jesus rising from the dead.
