Jack sent me this link that tests reaction times. He says his results are that he has the reaction time of a 27-year-old.
I'd had some wine a couple of hours ago. My reaction times were those of someone 49-52 years old. :(
But then I realized the instructions said to push any key, and I had been tapping the touch pad. So I retried the test. When pushing a key, my reaction times are those of a 29-32 year-old. They're not quite as quick as Jack's but I'll take 'em.
If only everything else about me worked like a 29-32 year-old.
