I’m a geologist who has spent at least 5 years exploring for gold in West Africa, my real love, however, is space and planetary geology, this means I spend half my time looking at the ground the other half looking at the sky… making me prone to walk into things.

I’m sorry, 2. please let me know so I can correct it.
