Death has been on my mind a lot recently. Can't seem to shake it. I keep thinking about the fact that in 150 years time every single person in the world alive now will almost certainly be dead, and then I put that into the context of the history of the Earth and...well it's not a jolly thought is it? More alarmingly, as I drift off to sleep I've started focusing on my breathing, realising that each breath I take is one breath closer to my last - another one has been used up. This kind of thinking isn't good for the soul, and I wish it would stop.
