Default Oxygen sensor - how long do last?

I have a 2004 f150 with 100k miles. Should I replace the o2 sensors as a maintenance item or wait until they fail?

How long do they normally last?

Some say replace at 100k . They drive your fuel mix ,very important . You can monitor them with torque pro /android phone/Bluetooth reader . You can see if cat working and o2 sensor moving etc .

I've had cars and trucks with over 300,000 miles on them with original 02 sensors.I'd just leave it alone. :-)
