When I was 16 years old my Grandad died suddenly, it was devastating for me and it took quite a long time to get over the shock. Eventually though you start to accept these things as he was old. However as I got older I realised he was only 66! To a 16 year old that was old now as a 37 year old I realise when I’m 66 I won't even be old enough to claim my state pension.
Perspective is a powerful thing it frames how we see the world.
