If you take care of it a bow should last for a long time. Really besides strings and cables the only thing you need to worry about is limbs. If your limbs stay in good shape the bow should be fine. Ive had guys bring bows to me wanting work done to them but I wouldnt dare try to press them because of how brittle the limbs were. Just do your proper maintanance and care and a bow should last for 10+ years.
