I’m slowly recovering from nearly a year of fatigue after having covid last March. I have completely forgotten now what ‘normal’ feels like. I think I have got an unrealistic expectation that when I’m better I will spring out of bed full of beans. I’m not sure I ever sprang out of bed 
So if you’re in your early/mid 40s, particularly if you’re busy (full time work, family etc) with no serious health conditions - how much ‘oomph’ do you have? What does your normal feel like?
