Driver airbag life expectancy?

[Rob175]

I own a beautiful (mint) 98' Boxster with only 69M miles on it and was wondering about the almost 20 year old explosive airbag in the steering wheel staring me in the face. Is there a life expectancy to the driver steering wheel airbag? I certainly don't want it to suddenly go off in my face while driving without a reason.

What are others with older cars doing? (forget about it?, replace it? remove or disconnect it? (if even legal).....or what?)

Thanks
