If you don't ride the clutch (on hills to save selecting neutral pulling handbrake on ) the clutch should easily last 150 to 200K. Just use the clutch for what it is meant for (changing gear and moving off normally) and you should never need to replace it ( unless it gets contaminated with oil ). I have experienced clutch 'judder' when pulling away - very slight on Jazz but Civic has been more violent - I just sat on the drive and put into first gear and deliberately slipped the clutch ( to polish the flywheel face) and clutch was perfect after - the only one of my cars that ever needed a new clutch was a Vauxhall Viva (say no more) - I did 190,000 miles in my 1996 Civic and original clutch was still perfect.
You do need to replace manual gearbox oil at 70,000 though, and bleed clutch hydraulics every few years to keep fluid clean and free from corrosive moisture ( brake / clutch fluid attracts and absorbs moisture - hygroscopic, which can cause corrosion in system - as well as making clutch and brake operation a bit dodgy). Probably the main cause of cylinder failure on clutch and brakes is water in the fluid corroding the metal.
