Question for pen collectors

[beer]

Do you use your "best" pens for every day "mundane" writing: filling out forms, work related letters, signing documents etc. or are they a hobby item that you use for "fun" writing (greetings cards, family/romantic letters or even just playing around on a sheet of paper)

If you don't use your best do you still have what most people would consider a high-end pen for everyday tasks ... similar to say a Patek owner wearing a steel Rolex Sub on a daily basis?

another question do pens get worn out? aside from having to replace the ink will a pen go on forever if it is treated correctly?

thanks in advance
