Absolutely! I saw it on the news last night, and I must say I would not have guessed his age if it was not mentioned.

His cardio is probably better than mine.. :D

Ahh, roger. Kinda strange that the article doesn't mention that.

Challenge accepted, I'm 34 though :) I really hope I'll have his mental and physical abilities at least.

It's baller, but I wish they would focus on the fact that a 105-year-old is doing what he's doing, not focusing on a "record" that's a 1/1 attempt. Add enough caveats and everyone's a record-holder in something.

Do you have to be alive to participate?

True. Many sports use that scheme.

For example:

- athletics: https://en.wikipedia.org/wiki/List_of_world_records_in_maste...

- swimming: http://www.fina.org/content/masters-records

- cycling: http://www.uci.ch/mm/Document/News/News/16/60/58/20160502_Ma..., http://www.uci.ch/mm/Document/News/News/16/60/57/20160713_Ma...

- cross-country skiing: http://www.world-masters-xc-skiing.com/en/rules-of-competiti... (section 601. I can’t find world records here; maybe they do not keep them?)

- rowing ergometer: http://www.concept2.com/indoor-rowers/racing/records/world

Concept2 uses 10-year ranges for ergometer records, likely because of the smaller competitor pool.

Having age groups keeps older competitors interested in taking part in races.
