In aikido, we learn both from applying the techniques and from receiving them. One cannot learn aikido by doing only one or the other. We also learn that aikido has the potential to do harm, and that we have a responsibility to understand how to practice it safely and beneficially - not selfishly or harmfully.

Thinking about the current coronavirus epidemic, one can look at it in two ways: first, what is my risk of catching the virus? Second, what is the risk of my passing it on to others?

Catching the virus is clearly bad for the individual, but passing it on to multiple other people is worse for the population as a whole. I would encourage everyone to limit their contact with others, so as to slow the rate at which the virus spreads, and help keep vulnerable people safer.
