How old is too old too keep skateboarding?

I found out yesterday that I qualified for the 2025 USA Slalom Skateboarding National Team at 65 years old. I would give up my spot to make sure Leiola gets in but I kind of want race in the World Championships in Brazil in November if I can raise enough funds to help pay for it. I'll probably skip the US Nationals in Colorado in September so I can take the time off from work and race. I have only traveled twice out of the country to skate in my entire 50 years of skateboarding. How old is too old to keep skateboarding? I think I will find out myself. Tony Alva is still ripping as well as Randy Katin and several others close to my age or older. What an epic life adventure.
