@Mzuri conditioning is the key, athletes play in thier 30s , near 40s some after 40s all based on conditioning, not age, find the time and slowly build yourself up and you can do those moves, it takes time, it takes time, but you can get there...now you may have to take time off your crypto analysis so:) ... get out there and dance on the roller skates
in terms of rollerskating, I like skateboarding plus roller derby. IN NYC many rollerskating rinks exists and I have been to a few, but that dancing on rollerskates or congenial activity on rollerskates never clicked for me
