The new/used kidney is still very happy and functioning properly after four months.
The problem now is the anti-rejection drugs make me vulnerable to infections, and I just spent a week in hospital battling streptococcal pneumonia. Although I'm on oxygen at home 24/7, I'm recovering well. I taught my two fencing classes last week with an oxygen bottle trailing behind me, which made for interesting footwork. Much of the instruction was while sitting down, and directing bouting was no problem, and I'm looking forward to the rest of the term being successful.
