I dunno, your body goes downhill quick and injuries are just worse so I kinda understand why an older skater might make the comment. I didn't think everything would change so fast . I feel like the energy I had at 35 was very different and easier to tap into than it is as I close in on 39. I started skating at 35 and could go for 4 - 6 hours 4 or 5 days a week easy. Now I'm good for like 2, maybe 3 hours of intentional skating a few days a week so the shift is very fresh in my mind. I also had a couple bad injuries that I def didn't bounce back from despite PT and have to work around now. This has all prompted me to tighten everything up to try and turn the clock back a little for a few more years. Ripping mid 30s at a professional level is pretty impressive tho tbh, even more so in skating where a lot of these guys don't do anything special to stay in shape like other pro athletes. The other side of 35 hits different even if you're not horrible to your body.
