I get the impression Vince doesn't exacly live to work and I'm not totally clear what skillset he would be bringing to bear. I'm sure he's a competant worker and all but no offence, Vince, I just can't understand why anyone would search you out internationally.
On top of which, your Kenyan visa would likely be contingent on your employer's continued satisfaction. In the event of termination, you could find yourself obliged to leave basically immediately. So they pretty much own you. Given that, and your not irreplaceable skillset, how well are they going to treat you?
On top of which you're like 50, man. Sorry if you're feeling unfulfilled somehow but you don't start a new life overseas at 50. You're old, you're not built for it, and you're walking into it holding no cards. So I'm going to say no. If you want to see Africa, take a holiday there.
