Disturbing the Universe

And breathe…

Having spent the last 5 days living between 10000 and 14000 feet on Mauna Kea, I’m now back at sea level and enjoying the balmy feeling of there being enough oxygen in the air.

When you’re on the mountain you don’t realise how much extra work your body is doing to make sure it gets the oxygen it needs. Yes, you notice when you walk up a flight of stairs too fast, but you don’t notice that your lungs are inflating more and that you’re breathing faster than usual.

Until you get down to sea level, that is.

Suddenly everything is much easier.

It’s a good reminder that we live in a sea of air, held onto our planet by gravity and nothing else. And we need to take some of that sea with us wherever we might wish to go.
