My son had decided I am now officially OLD.
In the UK on the BBC we have a facility where you can watch TV programmes again on your computer. You basically log on to BBC I.player and select the programme you've missed. I did this and watched the whole programme peering at a 3" x 3" screen in the centre of my laptop screen. When he asked me how I'd got on I said OK but the screen was a bit small.
No, I had not noticed the 'button' in the corner of the screen to enlarge the picture to the full size of the laptop screen. I remember when I used to read about people doing this kind of thing - now I'm doing it!
