Don't worry about that.
The cheap FE-5680 that have been around for a while have a couple of
years left at least. And even if they go out, you can revive them
with a hot air gun.
I must not become metastable.
Metastability is the mind-killer.
Metastability is the little-death that brings total obliteration.
I will face my metastability.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the metastability has gone there will be nothing. Only I will remain.
