Nothing works as well as it used to, but compared to those I know who are around my age -- upper 50's -- I look, feel and act younger than almost all of them. I don't have to take medication and I normally weigh only a few pounds more than when I was in high school, while many of the others are twice their former size, or more.
I voted for "A bit younger" to be conservative, but it took awhile for me to decide on that instead of voting for "Way younger". I'm somewhere in between, I suppose.
When I was 45 years old I ran the half mile in the same time as I did when I was in 9th grade. I've slowed since then and now I am closer in capability to when I was in 7th grade. So looking at it that way, I'm getting younger all the time.
