my advice, personally? if you're curious, get a Botox injection. it is temporary, exceedingly well-studied, and generally does not interact with any other precription medicine. If you don't like it, it will wear off, just don't get it again and you're gold.
however, do NOT get fillers done, because from what research has been coming out over the past few years, the general consensus is that fillers do not break down in the body, and merely migrate when the dermis loses tensity. you will almost certainly need to get them surgically removed, and that shit isn't as easy as just injecting it back out. Though, I understand that recent studies have opened up a method of using some new kind of radio wave mapping to determine where all the filler went so that they can actually suck it back out piece by piece.
that's all by bus, really. I live at the top of a hill that used to be used as a qualifier in a professional bicycling circuit. I tried getting up it on pedal power, it's just too much.
I got an eBike recently though, it really does make that hill a breeze.
