Create a dummy$/$binary variable that takes value $1$ if a person report doing any frequency of physical activities $($codes $1-4)$ and $0$ if never $($code $5).$ Hint:

Commands:

gen phys$\_$act$=1$ if vigact$>=1$ & vigact$<=4$

recode phys$\_$act $.=0$ if vigact$==5$

What percent of the sample never do any vigorous activities?
