Your not 70 are you, so you want to start another discussion on a40 odd year old can out perform teenagers.
That's still leave s the question of out perform them at what exactly, an older teenager who trains will out do you at most things , arguing that you can beat an unspecified teenager at unspecified things is silLy, I can beat most of them at pool, I can't catch them in a 50 yard cash playing 5 aside
If your insisting on average teen ager, you need to compare them with an average 70 yo
No, the original 'comparison' was that there are some people in their 60s and 70s who can outperform the average teenager.
To start on with a load of bollocks about 70 year old olympians and having to compare average with average is utterly in your own head.
You simply can't argue that something isn't true by changing the original premise and then using that as your example - unless of course you're supported by scope...
