"Old" is a descriptor. Old what, exactly? Is it about your body? Sure, it is getting older. Are you, the mind (and also soul if you accept frameworks that allow for those) also getting old? Answer that to yourself.
And while you're at it, try to help people who have seen fewer decades so far. There is much talk about generations this or generations that online, and aside from algorithm-made spam and flood there is some small kernel of truth - but the phenomenon is also caused by algorithms and greedy cynical men who control the machines the algorithms run on. You or I can't do much individually but perhaps even little things we can do can, as a whole, be a sufficient counterweight to the evil being caused by machines controlled by malicious individuals. Or are you too old for this?
