Is it just me - or should I be worried when...

• I know the keyboard shortcut to increase text size in Firefox.
• The first thing I do when opening a PDF is up the zoom.
• The first thing I do when opening up a Word doc is up the zoom.
• Sometimes I lose the cursor. Or the cursor hides from me. That must be it.

I refuse to believe my eyes are getting weaker. It must be the Internet's fault!
