My advise to you

my triathlon training has given mom a whole new set of things to be worried about. she calls about once a day to tell me about a new concern she has for my health.
"don't break a tendon," she cautions.
"alexa, you've never run a marathon," she reminds me.
and my personal favorite, "alexa, don't try to break any records!"

the other night, her own sickness reminded her of all the possible things that could go wrong with my health in the very near future due to this triathlon:
me: hi, mom.
mom: i'm siiick.
me: oh i'm sorry to hear that.
mom: yes.
me: why don't you go to bed early?
mom: yes i am. you need to rest too with your training.
me: yeah, i do rest a lot.
mom: yeah, and take care of your knees! do you think you can wear knee pads while you run? you need to protect them they are very important.
me: sure.
mom: and for the swim, what do you wear when you swim?
me: well i haven't actually done open water swimming yet, but we'll be in a lake and i'll wear some sort of suit.
mom: okay buy the best suit you can. don't be cheap on it! there are a lot of germs in the water. don't drink it either! it is dirty. and don't get distracted while you swim; you might choke. when you get out of the swimming, is there a place to take a warm shower? can you take a warm shower after the swim?
me: um, yeah.
mom: yeah, that would be good. and you should pack chicken soup.
me: right.
mom: okay good. and don't try to keep up with april! april is a very. big. girl.
me: okay, mom.
mom: okay i'm going to bed goodbye.

5 minutes later the phone rings again:
me: hey mom
mom: yeah-what about when you're biking? what if you fall off? do you wear elbow pads? do you think you should wear elbow pads?
me: i could wear elbow pads...
mom: yeah-and does your orthopedist know that you're training for a triathlon?
me: no.
mom: no?? you should tell her. will you call me this weekend and tell me what she said?
me: no.
mom: NO?!?! WHY WOULDN'T YOU TELL HER WHY WOULDN'T YOU DON'T YOU CARE ABOUT YOUR HEALTH AND YOUR HAN--
me: okay, i'll call her.
mom: okay thank you goodnight.

i'm not going to call her.
