Cape Town, South Africa Journey

I'm sitting at Heathrow Airport waiting for a long distance flight to Cape Town, South Africa. If anyone was to track my carbon emission for the past three weeks, it would be quite high since my travels have included flights from LA to London, Amsterdam, back to London, South Africa, London and then finally back to the States. This doesn't include any relocation flights needed to either South Africa or London. I don't think that I'm looking forward to the SA flight since it's about a thirteen hour flight from London... a sleeping pill will actually be needed for this flight. Although I'm a seasoned traveler, I still can't help but get nervous every time I get on an airplane. The anxiety seems to grow as I get older and I'm not sure where it stems from, silly anxiety. Anyway, I am really looking forward to Cape Town and I have a long list of things that need to be done while there: wine tasting, climbing Table Mountain, visiting the penguins, maybe some scuba diving and definitely, lots of walking and traveling. I am really looking forward to being outdoors for the next three weeks adventuring it (especially since the husband is going to be working, I'll need to keep busy). I'm also looking forward to being active again. I broke my toe a few months ago and since I am a neglectful person, the healing has been quite stubborn. It's now finally getting back to normal where I can walk long distances with only minor discomfort so I'm hoping that I can now start running and being active again...apparently lots of booze and no diet restrictions with limited activity due to the foot has yielded an unhealthy kime.
