I got turned on to the erg by my grandson when I was 61 yo. He coxed for me at Ergmania one year. I just came back from Boston, where I watched him graduate from Northeastern U. He was on their crew and I met his rowing buddies at the party afterwards.
What great fun to talk rowing with those tall strong 20ish guys! And encourage them to keep on rowing. I challenged them to do a marathon when they turn 62, like I did. Then they would be 3 times as old as they are now! The expression on their faces was priceless.
So, keep on erging ladies. The interpersonal rewards are great, in addition to the health benefits.

Me and my grandson
