now back to 25

Well, I just did 25 pushups. The last time I tried, it may have been around ten just a few days ago- and those were shaky. Just now, I did not get any shakiness until the last couple. I may have been able to push it to 30, but why bother? It is not like a PE instructor is breathing down my neck. I would like to consistently hit 25 at least. I am not sure why I could do more just now, but I have noticed a bit of improvement in my tremor in the last week or so. Maybe they are connected.
