Early morning

It is unusual for me to rise early simply because the time it takes to get me up and dressed. That said, today i was up and ready before the sun had risen high enough to be a bother or become too harsh. I had planned to photograph the Icelandic poppy & honey lily (extras)
Although i achieved this monumental feat, the effort has left me quite drained.
Why is this?
Wind and tall plants, blokes in wheelchairs do not mix.
