Perceptions of some risks, by my students (Fall 2011)

In class I asked my students
If your roommate said "I am going to ..... " would the thought risky immediately come to mind?
I am asking for your immediate reaction, rather than intellectual analysis of whether it is in fact risky. The data shows the percentage saying risky (by show of hands).

Example
0%: study in library
100%: bungee jumping from bridge.

Data

5%: learn to target shoot at a gun club
25%: learn to ride a horse
25%: take cross-country road trip with parents
40%: walk across campus alone at midnight
50%: learn downhill skiing
70%: try online dating
80%: buy motor bike for commute
95%: try ecstasy
