My physical came back – and all is good (heart, pressure,etc.) but my iron level is a bit low. So, very good news, as it explain why I had such a hard time doing the great wall hike. Easy to fix to. Scheduled for a few infusion of iron over next few weeks – and that should top me up. Iron controls the oxygen level in the blood – so it would have been a bit of an issue at higher altitudes. As it stands, few weeks it should be back up. I think energy level will increase, sleep quality, etc. – so getting bit of iron should be quite nice.
