Bootstrap sampling from empirical data, is this the best way to estimate the underliyng distribution?

I have observed an experiment where 500 individuals (one after another) touch surfaces in a room and then leave. So I have a data set of recorded number of surface contacts $n$ for each person. I need to make a pdf of this but not sure how best to do it:

This is a histogram converted to pdf:

Would you recommend using a bootstrap sample to calculate the pdf of this distribution by kdensity?
