I'm 21. I've had a few friends die in RTCs, and one from cancer - she was ten.
One died on New Year's Day this year, early hours, blindsided on the driver's side by another vehicle travelling all too fast on a country lane. Never stood a chance. Two other passengers, both have since made a full recovery.
My mother died when she was 42 and I was twelve. Whole range of health issues, diabetes, kidney failure, anorexia - she also smoked for forty years, but gave it up when she was forty. I was so proud. I always keep a picture of her and my Nan at Mum's wedding in my wallet. I often wonder how she'd view my life today - whether she'd be too keen on the idea of me setting off across a country on a bicycle. I reckon she would, you know.
I am well aware of my own mortality, having had a couple of close calls on my bike. But it's not something I dwell on. I will live my life as fully as possible, and so long as death is swift and painless, I'll be alright with that.
