Of course, like many our age, I displace more water than I used to. In preparation of the challenge, I have been doing them on my knees. I've grown wise enough to know that I don't have to impress anyone and will know when it is the right time to transition to doing them on my toes. As a barrel-chested fire hydrant, pushups are the one thing that I've always been able to do a lot of and had stopped doing them because I fell victim to laziness combined with busyness.
Having said that, it's sage advice and I appreciate it.
