Pablo is entering through a fairly decent window where he could be really productive. 5,6, 7 + years depending on injury of course. At some point in time, all "older" athletes have to pay a price for out past I think. I have stayed fairly fit for the last 50 years but the aches and pains just happen. I don't think that anyone is immune. back, hips, knees, shoulders ... all moving parts. The older I get, the more I tend to think about the quality of life I lead as opposed to just extending it.
