Habrahabr summary -> Profportret -> Sector

In the course of filling in the summary, the user inevitably gets to the “Sector” item, in the description of which is “Specify the sector in which you are working (or, maybe, you will work)” - then the list in which the choice is implemented by radio buttons, the only active option is possible.

But what about those who, by the nature of their activities, are involved in several sectors at once, and wish to reflect this in the summary? Maybe it makes sense to replace radio buttons with checkboxes?
