The age of a curse has no power or effect over an individual. You must first believe that the curse can be broken before any progress can be made though. A curse is normaly always a psycological weapon used against individuals that works by bringing the mind into bondage and believing that the curse is upon them. The mind is powerful beyond our understanding and as a result what one believes about themselves can actually be brought into actualisation and fruition. The Word of God Specialises in freeing the mind from all kinds of bondage by allowing you to see yourself the way God sees you and knows you. Once you begin to understand who you are in Jesus, no curse, regardless of its age or supposed power can hold you.
In cases where the curse is bringing about a physical manifestaion, the same applies. These physical manifestations are often brought about by the belief that a curse has been conceived when in reality, the curser has no authority to issue such curses. It is only when we realise that actually, this person has no power or authority that is higher than that of Jesus, Christ, that we can fully understand that a curse or the person attempting to issue it has no power.
Now, although the answer is simple, achieving this level of belief and understand is not. You are going to have to surround yourself with The Word and knowledge of God in order to attain and maintain your freedom from these assumed curses.Like someone before this response said, go to your church and get around people filled with The Holy Spirit and who understand these types of issues and have them teach you Gods Word and pray with you. Whatever your curse is, it cannot stand against God's Word in Jesus's name, amen!
