I shouldn't be ,but I would say it would be close if I had to be tested against mine.
And what happens when they reach your age now? It worries me for a lot of kids. One of my daughter's friends is quite large already, and only nine. No limits on her at all by her parents it seems, and while she is a great kid in many ways, what happens when she is 19, or 29? If on the current trajectory, she isn't looking like she will have a healthy life.
Yes it is worrying. I played competitive sports into my 30's and even with a back problem I an still in fairly good shape. When I start training again which I will do then I will hopefully drag them into doing the same. You are what you eat and yes I could eat better, but I know it is only 3 months to get back into shape. My son lost weight recently which was good to see and is looking fit yet fitness wise I am on a par. Parents need to help their kids help themselves and there are many over weight kids today that have no chance of ever being healthy.
Over a decade ago, my dad was visiting for his 75th birthday (he has passed now) and challenged one of my brothers (not here on Hive) to a sit up competition. My brother wouldn't take the challenge. My dad was in far better shape at 75 than his son at 43.
I could take that challenge and I am 46 now.
