Let's see... a full breakdown from the perspective of a not massively active british IT support worker...
Consider myself: Not physically fit, but not dangerously unfit. I can still climb several flights of stairs without needing a breather, run for... short distances, cycle somewhere at a reasonable pace if I need to. Actual fitness level unknown and untested.
Amount spent on vitamins etc: probably far less than that $8-ish average, unless it includes fortified cereals, juices, cold remedies etc. There's packs of vitamins and fish oil tabs etc that I dive into if I feel really worn down, but they're probably more than 2 years old now.
Don't actually have any "fitness equipment", unless you count my trainers (sneakers) and bicycle. Neither of which have stuff hung on them.
Resting heart rate is somewhere in the 65-70 range, which I know isn't great, but could be worse. Blood pressure's OK (funny that they don't include that, or a cholesterol/blood sugar/etc check?)
Maybe get an hour a week of identifiable exercise on average? More? I don't know. I do work on a sprawling, hillside campus with many stairs and ramps, and my job involves moving around it quite a lot - sometimes carrying or dragging equipment, as well as sedentary work in front of the PC (and goofing off at lunch of course). I'll do energetic cooking, some garden work, wash the cars, put elbow grease into other housework etc, occasionally have a bike ride somewhere on a chore instead of driving if the weather's good and the traffic's crap. But the longest sustained period may be a half hour at best.
Weight is about stable. I still fit all the clothes I had at university. It has wavered in between (gone down, gone up, gone down again slightly) but I don't think I'm at a point where fat is gaining and muscle losing ... for now.
If my genetics are anything to go by, I should be able to beat 77 years by a good chalk, so long as I'm careful. I will however agree with 23 as being the best year - just out of college in a lot of cases, or otherwise in an independent position where it's easy to live healthily and devote time to active pursuits.
Time to run a mile, god, I don't know. But that stated time is
less than five miles per hour. I can sustain a 3.5 to 4mph fast walk if really burning up the city street, and 12 minutes of jogging at 5mph is probably doable. Just don't ask me to do the second mile.
Am however definitely over the average weight on the chart (probably pushing 200lbs) and can't blame all of it on height (a shade under 6ft). No idea on chest size, push ups per minute, percentage fat, bicep size or all that crap. Waist size is a little over the average - 36~38" is generally what I fit.
As for the johnson... looks like I'll be alright, so long as there's a woman out there looking for Mr Average or slightly better
And why pay to watch hotel porn (and be surveyed doing it?) if you have your laptop? Come on.
Mind you I do have to bear in mind that's comparing myself against the average American. (Or "American Joe", I don't know if that's a particular subset they surveyed). Which one would suppose includes the infamously high proportion of flabtacular gutbusters and the full age range up into three figures. An interesting comparison would be to stack those figures up against other nations...
