You're 30. You're not qualified to speak on this until you actually experience it. When I was your age, I could dunk a basketball. Now, at 50, I can barely touch the backboard.
When I was in my twenties, I used to say stupid shit to the old timers who told me what to expect. I was wrong. So are you.
Bingo! I used to be young, dumb and full of cum myself.
I always imagined I'd be the exception and go on lifting heavy forever, free from joint issues.
Now at near 60 yrs of age I KNOW differently.
Cars, race horses and humans , all age and decline with enough time and mileage.
This is why it's rare to see pro athletes in their 40's and they are long gone by 50.
Track sprinters are one the best examples of this .
They stretch and warm up as good or better then most athletes.
They don't get hit or knocked around like football , soccer or hockey.
How many elite, world class sprinters are as fast in their 40's as they were in their 20's?
Granted a small handful have COMPETED at 40 but never run their fastest.
