What Have I Done Today? Another Milestone!

I consider today another milestone of my health progress.
Morning, I first drove to couple of garages nearby, quote the price of fixing my car. I also did some reading, and online discussion about my car problems. After lunch, I decided to do something by myself. So, I went to auto parts stores, bought seafoam and pour it into engine and gas tank. Then drove home, rest a little, then biked about 10 minutes. I still felt energy, so I decided to change spark plugs by myself. I drove to store again, bought parts, tools, and changed spark plugs by myself (with help of my neighbor, but at least I know how to do it completely!). So pretty much after lunch till 5pm, I had been in constant action. And during evening, so far (9pm) I didn't feel much tiredness.
This is something I have not done for I-don't-know-how-many years!

(On 09/17) "Punishment" does come today (actually since last night), but not too bad. All I need is rest a couple days.
