In my entire personal network, I think I know only 1 person who actually lifts weights. Why is this? I wonder (1) what percentage of my friends regularly work out and don't talk about it and (2) what percentage of these people lift weights versus doing other stuff. 

I imagine it's (1) 50% and (2) 5-10%.

it's sad because barbell strength training is the single most effective thing most people can do to improve their health

that and cutting sugar

yes

strength training is also cardio--during sessions, your heart rate is high

and it has more permanent advantages. for example, cardio burns calories once. building strength burns calories forever--your resting metabolic rate goes up with your muscle mass

still good to do both

Is it better than cardio? Running / swimming / cycling?

where are the unexpected places sugar hides in an avg. diet?

(i’ve cut out all the obvious ones)

source? (obviously it serves me if this is true, i just haven't seen this data)

imo the most effective order is something like:
flexibility/conditioning > strength+power > cardio

100% cutting sugar esp ketchup, mayo et al is a major unlock
