She is way too old for that!
Thats not good for her heart in that age(20 years).
And apparently, she enjoys it already enough, people already said that she looks way happier now, always smiling, again energetic and she even started
to play with her squeaky toys again just as she did when she was younger(just not all the time of course, but occasionally)

I'm technically not a hobbyiest, but I have been playing with chemicals since 14 or before, and still have fun with them. I started wanting to make
rockets and pretty colors in fire, got lucky enough to work in a real labs while in high school and college, which excited me more, but kept me too
busy to do much playing, but then once I finished grad school and got into a real job, I got back into habby type things, like photography (back when
it WAS a form of chemistry), pyrotechnics, even making my own pesticides, wood finishes, and much more. I still like to try physics experiments,
design new routes for known compounds, and try to invent new molecules to address needs.
But since I worked in the pharms industry for years, I just tell people that I make drugs, and leave it at that until they ask more. Sadly, while
many of my old coworkers have invented a drug that made into the clinic, but I never had. The odds are not good for that, only a small fraction of
chemists every discover a great compound, but since I know so many, it is quite rewarding to know that I at least put a lot of hits on goal.
So even when I do personal hobby type chemistry, I find it rewarding just to learn or solve problems. As well some things are just fun, distilling
ethanol, making a real fireworks and shooting it, formuating the finish for a woodworking project, making plastic for a student demo, doing a
chemoluminescent demo (loved doing that for years), and more. Maybe once I retire I can do more demos of chemistry to students, I used to do a
lot, but too busy lately. Sadly, much of what I used to see or do would now be tough to get by many safety people.

The best answer IMO is the same for all my hobbies(oh boy do I have a lot of hobbies that make no sense to most people) when people ask "why": Because
I like doing it. There's no goal.
Like, I've been trying for several months to find and refine ways to make sulfuric and nitric acid, for some far away foggy end goal of making maybe
nitroglycerine and other nitrated compounds. I recently came upon a way to cheaply buy both concentrated sulfuric and nitric acid, and suddenly I felt
that maybe I didn't actually want to. It'd get me one step closer to my goal, yeah. What if I could just easily and cheaply buy the nitroglycerine
right away...? I'm not sure I know what I would even want to do with it. I guess... uhh blow something up...? But I don't have anything that needs to
be blown up. Hmm. I think I'd just put it somewhere safe and lose interest at that point to be honest.
For those who still don't get it, I answer with a question: "why do you watch TV? What's your "goal" with that?". In the end watching TV is exactly
the same as anything else one does for enjoyment, although at this point it's hard not be a little bit condescending lol.

I think most people have a shallow understanding of chemistry. I usually respond by explaining they use it every day as well, I just seek a deeper
understanding so I can take advantage of it and perhaps create something unique. Most of my hobby centers around plating and electroforming, pigments,
dyes, oxidizing patinas, etc., because I like to integrate it with art. Below is a raccoon skull I electroformed with copper. I have done similar
electroforms capturing stones and other objects with nickel as well.

What do you mean by electroforming? Do you mean you electroplated a skull and other objects or you made a mold of the object and then plated that? Did
you use electroplating or electroless plating?

I don't know who invented mRNA vaccines but they should get a fancy medal and I hope they made a shed load of money from it.

I suppose it is technically electroplating but I use the electroforming term because the deposit is very thick and not adhered to the skull - the
copper can be removed easily if it were not encasing the skull as thoroughly. I usually use multiple coats of an aerosol graphite spray to create a
conductive layer and use a copper sulfate electroplating solution. Same with nickel electroforms I have done - start with a copper strike and pile on
the nickel. would like to try making a nickel electroform crucible someday. Eventuall would like to do some electroless nickel as it is easier to
plate a variety of materials.

I tried electroless nickel on glass with various substitutes for palladium activation but all failed. Perhaps depositing a silver mirror first
followed by a nickel strike then electroless nickel or just buy the expensive palladium chloride.

Never thought of trying with a silver mirror, I like that idea - I'm going to have to try that one day

Hobby
I don't have to explain my chemistry hobby.
My family and friends have known for a
long time that my favorite things are
energetic materials.
From opening of NCIS New Orleans - It goes a BOOM ! BOOM ! BOOM ! MUHAHAHAHAHAHAHA !
