That's the word on the floor in SYD but a quick search on google came up with this from Airliner.com:
These are not life limits but intended design limitations. The maintenance requirements get more and more significant with time. For example the number of cycles the A320 was designed for was 48000 cycles, but airbus has extended the maintenance program to 60,000 cycles and beyond.
