Am I fit for Africa?

Two weeks from now, I'm flying to Johannesburg. Two day later, I'm in the African Lowveld.
Of course, I tried to prepare as much as possible. Doing regular EMS training, walking a lot more, reading a lot about topics like wildlife conservation and usage of natural resources.
But somehow, it didn't quite work out the way I hoped it would. There are thousands of different topics that kept me distracted from concentrating just on my Field Guide training material (especially studying birds). And physically, I've had to interrupt my training for a number of weeks, first due to corona measures and in the last couple of weeks due to problems with a lumbago I suffered from. Also, I've had pain in my knees when squatting for a couple of years now, and have been worried about how that is going to effect me in an environment where trails can only be found on the ground and where toilets are not exactly what we are used to here in Western Europe.
I've had a complete physical check-up two weeks ago, and the doctor confirmed that I am topfit and good to go to Africa. But still, these little handicaps have kept me thinking quite a bit.
And then this morning, I woke up with a severe headache. Now I'm known to have a very slight form of migraine and react to weather changes every now and again. But still. It was bad enough for me to not feel well at all and so I decided to take and aspirin and go back to bed. I slept for another 2,5 hours and when I woke up felt a whole lot better.
And then in the cause of the day, it began to occur to me that all those little problems I've been struggling with lately, are almost certainly just signs from my body to cool down and relax. It's my body saying to me "take it easy. Don't worry. You're fine. Just stop trying to do even more things in parallel than you've been doing for so many years, only because you soon travel to Africa, and take it easy, because it will all be just fine."
So am I fit for Africa?
You bet I am!!
As fit as I'll ever be, looking forward to whatever comes to me.
If I don't get everything I wanted to do done before I leave, that's fine. I'll do them when I get back. Or maybe find there was no real need for them anyway.
If I don't know 30 or 40 birds by heart before I go? So what. Other people have started this adventure without knowing any birds and did well in the end. So can I. And I know I am not really very good at learning by heart (more of a logical thinker), but I'll have my full focus on it when in Africa, so I'll manage.
I am ready, I'm looking forward to it and I'll enjoy it every minute.
My body thinks so. So why would I question it?
