We're all getting physically older all the time.
But what's a way not to become old mentally? And I don't mean memory and thinking capcity - I mean becoming a boomer, someone nobody really wants to be around. Someone who's only friends with their wives. Some old mathematician who writes blog posts like John Baez. Somebody who's life is over.
How to avoid?

You'll find C represented in any C-vector space, so that's moot.
Also, the matrices he wrote down aren't in su(2). If the unity matrix were in it, SU(2) wouldn't even be compact (let alone unitary).

Are DNA tests too powerful?

If I had to guess, I think he posted Newtons method to find zeroes of a function, and which has some continuity requirements.
Meaning the sequence is the point in the recursion and the starting point is arbitrary

Here some more

[math] \sin(z) = z\prod_{n=1}^\infty \left(1-\left(\frac{z}{n\,\pi}\right)^2\right) [/math]

it's awesome, I agree

[math] \dfrac{1}{\sin(z)} = \dfrac{1}{z} + 2z\sum_{n=1}^\infty (-1)^n \dfrac{1}{z^2 - (n\,\pi)^2} [/math]
